Created attachment 49230 [details] Screenshot of bleed through Windows in KDE suffer from a pixel-width line of bleed through between the window content and its border. Does not happen with classic driver and I have not observed anything similar in XFCE.
This may have in fact been a bug in the xf86-video-intel package, because since upgrading that to 2.16.0, this bug went away.
Damn it, I spoke too soon.
Magically fixed! <fingers crossed>
For the record: Do you have a guess what fixed the problem?
I presume that it happened in a recent git pull of mesa, BUT it might also have been upgrading xorg-server from 1.10.2 to 1.10.4. I actually tried to downgrade mesa in order to confirm what fixed it but ran into a problem. If you're interested I'll persist and get an answer for you.
