Description Daniel van Vugt 2017-07-17 06:16:59 UTC
es2gears_wayland only achieves 40 FPS (in Weston and Gnome Shell). Or to be more precise: 39.968 FPS.

Meanwhile, es2gears/es2gears_xll achieves a smooth 60 FPS (under Xwayland which comes with Gnome Shell).

mesa: 17.1.2-2ubuntu2
kernel: 4.11.0-10-generic
weston: 1.12.0-3

Oh wow, eglut_wayland really was super broken. Fix on the list:

Thanks for the report!
Comment 2 Daniel Stone 2017-07-17 11:03:19 UTC
FWIW, weston/clients/simple-egl.c (and simple-shm.c for software rendering) is a _much_ better reference client than the Mesa ones; eglut really is a pretty terrible interface.

Fix pushed to master now.
Comment 4 Daniel van Vugt 2018-01-24 03:29:00 UTC
Thanks. It looks like mesa-demos hasn't had a release for 2 years...


So this fix still isn't released either. Any idea of when a release might happen?
Comment 5 Daniel van Vugt 2018-03-07 03:46:09 UTC
Fix released in mesa-demos 8.4.0
