Random white screen in cluster view requiring app reload

[SB-MFJ]

Describe the bug

Randomly, the whole app turns white when doing anything in the cluster view.
Need to force reload and connect to the cluster again

To Reproduce
Steps to reproduce the behavior:

1. open the app
2. go to cluster view
3. navigate around for a little (usually within 30 seconds)
   1. you can also just leave it open for a minute or two, and it will also white screen
   2. nothing in the developer console either, but now the screen will be gray. So maybe like the page electron is serving disappears, but the wrapper is still up?
4. white screen of death

Expected behavior
Expected to not hang and needing to reload so frequently

Screenshots

Desktop (please complete the following information):

• macOS Sonoma 14.5
• Monokle 2.4.8

Additional context
We have about 2586 resources which I don't believe is that many, k8 1.30.3
The app was a little slow when first starting out, so I disabled some of the validation checks to get moving for now.

Side tangent: Where does the CPU/RAM data get pulled from?

hi @STV-MFJ - thanks for reporting and sorry for the troubles you are having.. what kind of cluster are you connecting to!? is it local or remote?

regarding the CPU/RAM data - i'm not sure - perhaps @devcatalin can help?

This is an AWS EKS cluster

Hi @olensmar

I'm getting the same as @SB-MFJ. My clusters are VMWare Tanzu with k8s 1.28, I'm running on a M3 Max / 64GB under Sequoia 15.0.1.

Started Monokle from the terminal and got the below trace, reproducible.

As simple work around is to start Monokle from the terminal with increased memory. 4GB RAM seemed to work for me, but others may need bigger or smaller values.

cd /Applications/Monokle.app/Contents/MacOS
