Black Artifacts/Pixels #3865

System Information:

Problem details:

Screenshots: Github1 Github2 Github3

The only "fix" I have found so far is by using the -opengl4 flag.

Do these artifacts also appear in imagery saved to disk, e.g. like in the tutorial example?

syveqc commented 3 years ago

I can confirm this issue with vulkan (although to a bit lesser degree on my machine) and that it is present in imagery saved to disk, I attached an example of an RGB-Camera saving to disk using cv2. In my experience it greatly varies when restarting carla, from really annoying to barely noticable, but the artifacts are always there.

Edit: Uploaded it to youtube since my browser won't play it here: https://youtu.be/bBWxd_C9who

@qhaas As pointed by @syveqc the artifacts also appear in the images saved to disk.

Hi all, this is an issue that happens with some of the newer gpus (such as rtx 3080) when using vulkan in Unreal Engine 4.24. This is an unreal-driver issue that seems to be fixed in the latest version (4.26) and we plan to switch to that version for the next release.

That is good to hear, looking forward to official headless/displayless vulkan (Issue #3800), fixes to this issue's artifacts, and the OpenGL artifacts of Issue #3377.

On the chance that an upgrade to UE 4.25.x fixes the OP's issue, we got CARLA 0.9.11 (unofficially) working with UE 4.25.4 over in Issue #3214

Update: CARLA 0.9.12 is out, that is based on UE 4.26.x, so headless vulkan is working now, but some gpus / drivers appear to be still having similar issues

I am also having this issue:

The issue occurs with and without the -opengl flag. This image has also been saved to disk.
