<pre>I have tested drm-tip from 2018-04-25.
The situation hasn't changed.
I guess I should have opened it as soon as the regression was introduced,
unfortunately I was using Debian at the time. The machine is old now, and I
imagine it is going to have less and less attention from the developers.
I still don't know why the frame rate is halved. Is it the drm or
gnome-shell/mutter/clutter? I wish I could help, but I am not sure how to debug
this.
I only know that my experience with Gnome was very good with Debian Jessie and
UXA (hence the bisection). So I assume the hardware is capable enough.
KDE Plasma doesn't have this issue at all, in any mode (modesetting, UXA,
SNA...).
I also don't have this issue on a Sandy Bridge. Only on my Ironlake.</pre>
