Buggy rendering for Forward+ and Mobile in Editor with Vulkan 1.4

[A-S-Rock]

Tested versions

• Reproducible in: v4.4.beta2.official [a013481], v4.3.stable.official [77dcf97], v4.2.2.stable.official [15073af], v4.1.4.stable.official [fe0e8e5], v4.1.stable.official [9704596], v4.0.stable.official [92bee43]

System information

Godot v4.3.stable - Windows 10.0.26100 (Windows 11) - Vulkan (Forward+) - dedicated NVIDIA GeForce RTX 4070 (NVIDIA; 32.0.15.7216) - AMD Ryzen 7 2700X Eight-Core Processor (16 Threads)

Issue description

Completely new to Godot, I followed Brackey's tutorial and found weird behaviour in the editor and sprites. These only manifest in Forward+ and Mobile using Vulkan, Compatibility works fine. Considering I have a RTX 4070 which supports Vulkan 1.4, I tried the same project on another machine (Dell laptop) which only supports Vulkan 1.3 and no buggy behaviour appeared.

To confirm this on my current computer I downgraded the GPU's driver to the latest driver only supporting Vulkan 1.3 and the buggy things disappeared. So, my current conclusion suggests the cause being Vulkan 1.4. I tried multiple stable versions and all from Godot 4.x show the same thing.

Resizing the window changes the buggy lines' appearance, but most of the time they don't vanish.

Video showing the behaviour which I expected watching the tutorial (with downgraded GPU's driver and Vulkan 1.3 on Forward+ in v4.3.stable.official):

Video showing the render bugs on the editor window (especially visible on the sprite animation, the left borders of the "Scene" and "FileSystem" and the "Change Split Mode" icon"):

Screenshot and marking the anomalies:

Steps to reproduce

• Without a project:

  1. Open Godot v4.x with or without console.
  2. Create a new Project and use the Forward+ renderer.
  3. After the start, the render bugs in the Editor window as shown in the screenshot above already appear.

• With a demo project:

  1. Open Godot v4.x with or without console.
  2. Open the demo project.
  3. After the start, render bugs appear in the editor and on the sprite as shown in the videos and screenshot.

Thanks for the report. It seems to be a duplicate of #102219. The latest Nvidia drivers are broken.
