Description Olivier Fourdan 2021-06-28 08:28:06 UTC

Description of problem:

Xwayland (and many other components) rely on libepoxy, but the version we ship in el8 is a bit old and does not contain support for some of the recent API.

Typically, EGLstream support requires `eglStreamFlushNV` shich is not in libepoxy 1.5.3 as found currently in el8

Version-Release number of selected component (if applicable):

libepoxy-1.5.3

How reproducible:

Always

Steps to Reproduce:
1. Install NVIDIA driver
2. Enable Wayland with NVIDIA driver
3. Log in a Wayland session
4. Run xterm
5. Resize xterm

Actual results:

The window goes black at times

Expected results:

The window is fine

Additional info:

This is bug 1976132 and in the journalctl logs we see:

"EGL_NV_stream_flush not available, this may cause visible corruption."

This is because "eglStreamFlushNV()" is not available in libepoxy 1.5.3 as explained in the merge request upstream:
