           Summary: [r600c/evergreen] KWin Present Windows effect
                    extremely slow and has graphical glitches
           Product: Mesa
           Version: git
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: Drivers/DRI/R600
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: jlp.bugs@gmail.com


I've just tried the opensource Mesa driver on this eMachines E640G laptop with
integrated ATI Mobility Radeon HD 5470. I'm using Linux kernel 2.6.36 RC5. The
problem is, that desktop effects in KDE Kwin 4.5.1 work quite OK (a bit slow)
but one effect is extremely slow: the Present Windows onw. When I trigger it,
it takes about two minutes until all open windows on the current desktop are
shrinked so they are simulatinusly shown. This was with only two Konqueror
windows open. After the windows were shrinked there was also a problem that
they had a lot of red dots all over them.

If the CPU is pegged during those two minutes, a profile from sysprof or
oprofile should be interesting.

Otherwise, it might be interesting to (from a remote login) attach gdb to the
kwin process and during those two minutes get backtraces at regular intervals,
to see if there's any particular place(s) where it ends up most of the time.

P.S. The attached dmesg doesn't seem to contain any DRM related information,
maybe you can find it somewhere in /var/log/ .

I just connected to the laptop with ssh and triggered the effect and I couldn't
see any high CPU usage during the test (at least with htop)

I can confirm general slowness with ati mobility 4570 and open driver (using
xorg-edgers ubuntu ppa and latest 2.6.36 kernel from mainline). I read about
problems using blur and lanczos effects on kde 4.5 and disabled blur, as
lanczos cannot be disabled (afaik). I also turned off vsync for kwin as i
noticed this has increased performance. Present windows effects is at 6fps also
for me.

I'm running only r600g for some time now and it appears to be fine with it on
Evergreen. I can also try r600c if needed, but only after a few hours.
