Public bug reported:
On Mesa 20.0.4, the Intel Iris driver is affected by an issue with
selecting the appropriate dma buffer format on Wayland
(https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/4869).
This issue will prevent using most OpenGL applications on Wayland. You
can check if you are affected by this issue by running
`es2gears_wayland`. On affected systems, this will fail with `error 7:
failed to import supplied dmabufs: Unsupported buffer format 808669784`.
This issue has been fixed in Mesa 20.0.7. Please consider backporting
this version to Ubuntu 20.04 and 18.04.5.
