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.
