What were you trying to do that didn't work?

I was running glmark2 with Zink on a radeon GPU and I was receiving these errors:
[build] use-vbo=false: FPS: 890 FrameTime: 1.124 ms
Error: glXCreateNewContext failed
Error: CanvasGeneric: Invalid EGL state
Error: Failed to add vertex shader from file None:
Error: Failed to create the new program
[build] use-vbo=true: Set up failed
Error: glXCreateNewContext failed
Error: CanvasGeneric: Invalid EGL state
Error: Failed to add vertex shader from file None:
Error: Failed to create the new program
After a lot of time debugging Mesa, XServer, and XCB, we found that the issue was caused by libX11 not being compiled with thread-safe.

What is the impact of this issue to you?

Applications (like glmark2) fail at random.

Please provide the package NVR for which the bug is seen:

libX11-1.7.0-9.el9.x86_64

How reproducible is this bug?:

Steps to reproduce

1. Compile glmark2
2. Run `MESA_LOADER_DRIVER_OVERRIDE=zink glmark2 --size 1920x1080`
3. Wait until it fails
