Qt Vulkan examples crash in WSL2
-
I'm using Rocky 9 under WSL2 (llvmpipe rasterizer). The subject symptoms don't happen on Windows or in RHEL 9 under VMware.
To reproduce:
- Use qmake to setup the hellovulkanwidget example and then build.
- Run hellovulkanwidget and resize the window. If you keep at it for a while, the vulkan surface will stop rendering while the rest of the application continues to resize normally.
- Close the application. It will segfault.
I suspect that the issue is with vulkan, but I thought it was worth a try.
Strange rendering issues are actually common to all the vulkan examples on WSL2.
