Bug ID: 98369
Summary: gnome shell slows down after boot
Product: xorg
Version: unspecified
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Driver/AMDgpu
Assignee: xorg-driver-***@lists.x.org
Reporter: ***@gmail.com
QA Contact: xorg-***@lists.x.org

Rx 480 card, running on Linux 4.8.3. Gnome 3.22.1, Mesa 12.0.3.
When I first boot up the machine, everything runs great, gnome shell animations
are smooth, scrolling in most programs is fast and stutter free.

But after a few minutes everything goes downhill, gnome shell animations and
scrolling in chrome becomes so slow. Stutter everywhere. I think card goes into
a very low clock speed and never goes up.
Let me know if I can provide more information in form of logs or back traces.

Thanks.

Have you manually disabled DRI3? Could you try to enable it as a workaround?

This was Archlinux default configuration.
I did enable DRI3 but it did not had any diffrence on Gnome shell performance.
But I noticed scrolling lag on applications are gone. I was also able to play
CS:GO with very playable framerates. (Don't know if it was DRI3 or recent
Archlinux kernel updates)
I'll open up a bug for gnome-shell to see what they have to say.

If that is the case, it should be evident from watching the contents of
/sys/kernel/debug/dri/0/amdgpu_pm_info before and after the problem occurs.

Is this still an issue with current kernel & Mesa?
