[Pkg-xfce-devel] Bug#380639: xfwm4: Huge performance leak with the new beta 2

[info at noctus.net (Mathias Brodala)]

Package: xfwm4
Version: 4.3.90.2-1
Severity: important

With beta 1 of Xfce I switched from XAA to EXA as rendering method and
gained a large performance boost. My windows are set to become
semi-transparent on move and with EXA this is very fast even on large
windows with a lot of content.

But since upgrading to the beta 2 the performance boost is lost again.
It is even slower than using XAA. If I move a window now, Xorg catches
all cpu cycles and a almost 100% usage. The window itself is moved far
behind my actual cursor movement.

I am sorry that I am not able to give more information, so please ask
for anything you need.
