Bug ID: 89815
Summary: DRI3 and EXA: scrambled output when switching monitors
Product: DRI
Version: XOrg git
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: DRM/Radeon
Assignee: dri-devel@lists.freedesktop.org
Reporter: h.judt@gmx.at
I am using compiz-0.8. With DRI3 enabled in xorg.conf and AccelMethod EXA, the
output becomes scrambled when switching monitors.
This does not happen with DRI3 off and AccelMethod EXA,
and does not happen with DRI3 on and AccelMethod glamour.
There seems no proper way to restore functionality except killing compiz
(leaving a black screen) and starting another window manager, like xfwm4. After
that, launching compiz again is not possible, I have to restart the X server.
Using xf86-video-ati git master (391900a670addec39515f924265bfa9f8bfa9ec0).

Please attach /var/log/Xorg.0.log and the output of dmesg, preferably from
after the problem occurred.
What does "switching monitors" mean exactly?

There is nothing strange in dmesg.
The image looks scrambled and is frozen, yet slightly reminiscent of the
original screen.

Also, a similar issue occurs even with glamour + dri3 (and maybe exa + dri2
etc., but I haven't tested this) for:
xrandr --fb 3840x1200 --output HDMI-0 --mode 1920x1200 --scale-from 3840x1200
--output DVI-1 --off
And the scaling does not work. It recognizes the fb change (the panel pager
reflects this), but the scaling does not change. I've filed a bug for this some
time ago, though things have changed a bit since then:
