Black or wrong image thumbnails

[McLoo]

#4612 and #4599 Spin-off

Just opened a convo with last message = outgoing text+ image message
Preview thumb in convo list showed up fine
In-convo the (attached from attachment drawer) image thumb is black
Reproduced two times now, on 2 tries opening the said convo

More info

• group message
• thumb was fine after sending (which I'm pretty sure of, but not 100% 😞 )
• image MediaPreviewActivity shows the image correctly
  EDIT: no more true! Now the image shown is one I sent in some other thread!

[McLoo]

• AND after forwarding that message to the same convo, the CORRECT draft preview shows up 😕 (Log and screenshot with update)
• sending that draft brings the correct preview thumb up along with the correct MediaPrievewActivity view
• The first preview thumb is still black, but now shows the correct image in MediePreview 😕 😕

logs and shots follow in next comment

potentially fixed by #4737

A bit confused with these seemingly related issues so I'm just gonna leave this here.

I received a screen shot in a 1:1 conversation. I did not go to the conversation on my phone until more messages had come through and the said image was scrolled out of the view. So when I finally wanted to see the image I opened the conversation, scrolled up to get to the image and the thumbnail showed black. (Notice the cut out corners?)

The image itself shows without any problems.
But the thumbnail is still black.

Picture dimensions 720 x 1280. It's a png screen shot taken with Moto G (2nd gen) running Lollipop and Signal 3.5.2.

The receiving device (mine) is Nexus 4, 5.1.1, Signal 3.5.2.

[2-4601]

I don't have the issue with the thumbnail above any more after updating to 3.6.0. 👍

[mcginty]

🎆

[merkste]

I am running Signal 3.6.1 and experiencing the problem right now. Please reopen.

[merkste]

Additional info: Restarting the device did the trick to make the thumbnail reappear. (temporarily)
It appears to happen only to shared messages. As far as I can tell, only last shared message thumbnails gets displayed and all previous thumbnails turn black.

[McLoo]

@merkste maybe you could upload a log after you created a black thumbnail. And after you reentered the conversation that holds that black thumb.

Is the image correctly shown, when you tap/open it?
What is shown in the conversation list? Blackness or the correct thumb?

[merkste]

Weird, even more thumbnails turned black now. It happens in older conversation, too.

@McLoo If I tab the thumbnail, the picture ist shown correctly. In the conversation list I did not yet see any black thumbnail.
Logs are immediately after the action described.

1. startup
   https://gist.github.com/anonymous/0b0ccaa42f0e7760c9a9
2. opening a conversation. Last thumbnail is fine, older ones are black.
   https://gist.github.com/anonymous/7ae8345ebd97ac1fcbab
3. composing a picture message: preview thumbnail black, thumbnail after send correct
   https://gist.github.com/anonymous/67e7dd18d7b8273fe878
4. forwarding a picture message: preview thumbnail black, thumbnail after send correct (some messages received in between)
   https://gist.github.com/anonymous/edb50edc147ba51aacac

In steps 2 - 4 I had to reenter the suspicious conversations

[merkste]

Will you reopened this issue or should I start a new one?

[2-4601]

3.7.0, Nexus 4, stock 5.1.1
I was scrolling an old conversation and encountered this again.
But it seems this happens in every conversation I have: eventually at least one thumbnail will show as black if I just scroll back enough (I don't have to go past the 'See full conversation').

@mcginty do we know what commit introduced this?

[mcginty]

unfortunately no and still no repro on my install :/

[Wopfi]

I noticed something that may be related: After browsing "All Images" in a Conversation (with lots of images), the a wrong thumbnail image is displayed for the latest post. Tapping on the post brings up the correct picture but the thumbnail remains wrong. And by wrong I mean a thumbnail belonging to an older picture posted in the conversation.
It also happened to me that the thumbnail got totally black under similar circumstances.

Don't know if my log is helpful here but: https://gist.github.com/anonymous/ee23b39dc4a347732996

[peterpanondrugs]

• select attachment -> camera -> take picture, send it -> black thumbnail.

[kb100]

I'm also having this issue in 3.8.1. It seems to only happen with high resolution images.

[scienmind]

It seems that there is something really messy going on in the database:
Today this weird thing happened:

1. receive image from A
2. reply text to A
3. send location to B
4. exit Signal (not kill, just switch to another application)
5. enter Sinal
6. open B's conversation (the one with sent location) - everything looks good
7. open A's conversation (the one with received image) - instead of received image thumbnail, location's thumbnail from B's conversation is shown.
8. click the location thumb - correct (non-location's) image is show
9. get back to the convo - the thumb is still incorrect one (location's).

At some point the issue disappeared (unfortunately, i don't have a log for that)

Then, trying to reproduce it by jumping from convo to convo, black thumbnails appeared instead of correct ones....
Here is the log for the black thumbs (not sure though if there is anything useful inside): https://gist.github.com/anonymous/f8efa5acc8e32bc43c6f

[gerdneuman]

I also see black image thumbnails from time to time. Pressing the images always displays them fine.

Yesterday, in a group of 6 people one person (sender) shared a about 7 images and one movie. Don't know if related: The messages were sent at night from the USA, we opened them next morging in Germany. So there is a "time delay" maybe.

On my phone (Samsung SIII mini), about three of these images were black as thumbnails:

On a friend's phone (Samsung SIII), only one image was black. Interestingly, it was another image than on my phone. That is, same images sent but different ones showed up as black at the recipients.

@mcginty With which Signal version comes the above mentioned glide update to 3.7.0? Signal 3.10 or Signal 3.11.1?

[agrajaghh]

@jnachtigall there hasn't been a patch yet. First rule of open source projects: never ask for an ETA 😜

[jnachtigall]

Seems like the glide update comes with Signal 3.12. moxie commited 2 days ago: 170a429 Thx! ❤️ If the bug does not reoccur, we might close it after some time...

[2-4601]

I went through all my conversations 😰👉📱

Bad news: Found a black thumbnail:

Good news: It was only one. Before there was at least one black thumbnail in every conversation

Nexus 4, stock 5.1.1, Signal 3.12.0

[cbarnsdale]

I'm still getting this for about 50% of images. Low res, high res, doesn't seem to matter. This is anecdotal, but this only seems to happen in groups for me.

[jnachtigall]

Same here: With Signal 3.12.0 the black image thumbnails are gone mostly (for newer images), but some older ones remain black (images sent 3 weeks ago or so). Also only ever seen it in groups.

[Dyras]

Same here on two different phones!
Moto G (2015):
https://gist.github.com/anonymous/458ac938e1cd7fb7b628
Galaxy S5:
https://gist.github.com/anonymous/5053faff4fe592d2bac6

By the way, this was 1 on 1 with no groups involved

[Diapolo]

I also sometimes had black pictures, when changing a groups profile picture. Not sure if related, when I want to send images, not all are shown, the preview is empty like some caching which doesn't update.

[cascheberg]

Maybe check bumptech/glide#738

[piratenpanda]

This just happened suddenly on 3.16.0 and spreads through all conversations. Preview is black, turns into real image after sending. Thumbnail will turn black after a while, don't know what it takes to turn it black though

[zoff99]

+1 i see the same thing on 3.16. (on CM 12.1)

thumbnail was correct, after a while it suddenly turned black.
when i click the real image is correct every time

[wischi-chr]

Happend to me yesterday (3.19.0) after sending some Bitmojis. Now many thumbnails are black or turn black after some time.

[btittelbach]

Might be related to this bug (or might not)

Signal Version: 3.20.4

Sent an PNG exported from Inkscape via desktop client to a mobile client.
png on desktop client looked fine while background of png on mobile client was black and cropped.

On Desktop

On Mobile

[haffenloher]

@btittelbach it's probably only the thumbnail that is cropped. The black background is, I think, due to your image being transparent (not related to this issue)

[Thynix]

I've been encountering (and continue to encounter) partially-black (some portion starting from the bottom) image previews within the conversation but pressing on them displays them correctly. This seems distinct from the fully-black previews others mention.

Just now I encountered the wrong image being displayed in the image preview within a conversation. (I sent an image in that message, but the thumbnail displayed is the latest image I sent in a different conversation. The target is single-recipient SMS; the source is single-target Signal.) I'm using Signal 3.22.2. Is there more information I can provide?

This is really bad. Happened to me just now with Signal 3.25.4.
Started right after someone send me a picture taken with his phone.
Now all my thumbnails (in all conversations) are black. How to fix this?

Some more findings:

1. All previews are black
2. Taking a picture from within Signal shows a black preview as well (before sending the picture)
3. Deleting the picture without sending it and repeating step 2 shows the preview
4. Some older previews got back. Not all of them.
5. Choosing 'All images' from the menu and all black previews are gone BUT the previews are wrong now. Actual picture and preview is not the same...
6. Waiting a while and all the previews of the pictures I received are black again. The ones I sent are still fine.

4ad989c improved the situation (the quota of black previews has decreased), but this is still not fixed, some are still black. Conversation partner is on 3.24.0 (android7) and has no black previews at all, i am more or less on 4ad989c (android6) and still have black previews.

Restarting signal/the entire phone has no effect.
