Hello everyone,

When I'm baking textures using Labs Maps Baker and with the viewport set to Vulkan, once the rendering progress window closes, X11 freezes for several seconds. At the same time dmesgprints out the following timeout message:
Then X11 becomes responsive again.

Now, if it was the first texture bake since the start of Houdini session, control over the program will be restored, but the viewport will be botched. It will display only some parts of geometry, regardless of which operator has the display flag, or will not render anything at all. If it was the second bake since the start of Houdini session, Houdini will freeze completely and its process will have to be killed.

The problem I'm describing does not happen with OpenGL viewport.

I did some digging and found two threads on NVIDIA forum that I think are related. Even though they both started in 2022, they're still very active:

• Xid109 CTX SWITCH TIMEOUT Driver Crashes In Many Applications [forums.developer.nvidia.com]
  
• Multiple CUDA/RTX/Vulkan application crashing with Xid (13,109) errors [forums.developer.nvidia.com]
  

Has anyone else experienced this bug on Vulkan?

Houdini 20.5.278, RTX 3070 (550.54.15), Debian Bookworm (GNOME/X11).

I have having similar issue with the viewport crashing mu Houdini after a bake. But on Windows 10 .. Yes, im with Vulkan too, because even if performance could suffer, i noticed things like copernicus were not updating as expected

By the way, is it on the Sidefx roadmap to update the LabMapbaker with Copernicus?
