[SOLVED] KWIN_GLES - problem with switching between displays.

Hello,

I have problem with switching display between notebook and external display in KDE 4.10.1 with kwin_gles compositor. Setting dual display (left/right/above) or switching between displays causes broken screen and heavy cpu load (100%) for kwin_gles process.
When I change compositing type from OpenGL to Xrender or change kwin_gles to kwin, everthing works fine. But kwin is slow for me. :-(

Does anyone same bug?

- System is up to date
- KDE 4.10.1
- GPU ATI x1400 - driver radeon

Thanks

Apparently this is a bug other have run into as well. It's on the Arch and the freedesktop bug trackers:

Re: [SOLVED] KWIN_GLES - problem with switching between displays.

Can someone try use kwin_gles with dualdisplay settings? I mean switching between displays when one is in position right-of or left-of.

Thanks.
