first example, just strange colors, that come from stuff behind PlaneShift window

Since some time (maybe Mesa 10 and Linux 3.13) I have a new graphical glitch in PlaneShift.

When compositiing is enabled in Kwin as of KDE SC 4.12.2 grass and trees have areas with trees or grass that stuff from windows behind the PlaneShift window.

If I disable compositing in KWin the glitches go away. I will upload some screenshots in a moment.

This is with ThinkPad T520 Intel gfx only:

Kenneth, I am assigning this to you from Ian, as you took care of some of my PlaneShift reports from quite some time ago.
Comment 3 Kenneth Graunke 2014-04-13 20:46:59 UTC
I'm guessing this is probably the same issue as #74980.  Not marking it a duplicate though because I'm not sure.
Comment 4 Kenneth Graunke 2014-04-26 17:05:35 UTC
Hi Martin,

Can you try upgrading to xserver 1.15.1 or 1.14.6?  I believe that may fix your issue.

Comment 5 Martin Steigerwald 2014-04-26 17:29:08 UTC
I have xserver-xorg-core 2:1.15.1-1 already on this Debian Sid machine. And I really think I didnĀ“t see this since quite a while.

Thus I set it to resolved/fixed. If I see it again, I reopen it.
