my Xorg.0.log
Hi, I am using an MSI R7 260x OC with the new amdgpu driver. Everything seems
to run fine (I have yet to experience any crashes), however there constantly
flicker some artifacts on my screen.
In the Xorg.0.log I have noticed many suspicious error messages similar to
this:
AMDGPU(0): amdgpu_dri2_flip_event_handler: Pageflip completion event has
impossible msc 100169 < target_msc 100170
Looking at the description in the source code, it fits the bug I experience:
<span class="quote">> Check for too small vblank count of pageflip completion, taking wraparound
> into account. This usually means some defective kms pageflip completion,
> causing wrong (msc, ust) return values and possible visual corruption.</span >
I saw there was a similar bug (<a class="bz_bug_link
bz_status_RESOLVED bz_closed"
title="RESOLVED FIXED - slow rendering & fullscreen results in stale images"
href="show_bug.cgi?id=91540">bug#91540</a>), but it has been marked as fixed some
time ago.
My config:
Linux v4.7.2 (amdgpu, cik and powerplay enabled)
xf86-video-ati v7.7.0
mesa v12.0.1
xorg-drivers v1.17
xserver v1.17.4
KDE Plasma 5 (kwin)
If you need any further info please ask.</pre>
