Bug#777263: kde-window-manager: KWin crashes at logon on i965 graphics system with desktop effects enabled
Package: kde-window-manager
Version: 4:4.11.13-2
Severity: important
After a recent update to one of my Debian Jessie laptops (the one where I
actually use KDE all the time), I started to get annoying KWin crashes at
logon, with undesired consecuences (desktop effects partially working, the
panel appears at the wrong edge of the screen, panel is rendered completely
opaque instead of the partial transparency effect I've set).
Here is one of many of the stack dumps I get on one of those many crashes.
Looks like the KWin compositor is doing something that disturbs the i965
driver, therefore leading to a crash.
Application: KWin (kwin), signal: Segmentation fault

Changing the composition type between OpenGL 1.3/2.0/3.1 on Desktop Effects
advanced settings does absolutely nothing.
Temporary workaround #1: Logoff then logon again. Unfortunately that's not
working anymore after a few logons, and I can get a crash on every new KDE
Plasma Workspace session.
Temporary workaround #2: Disable desktop effects. Ugh, not something I want to
do. I love my eyecandy, and it was working just fine until recently.
Temporary workaround #3: Set GL rendered to EGL (KWIN_OPENGL_INTERFACE=egl)
somewhere in my .xprofile. This seems to fix the issues, but there are some
minor graphical glitches with EGL on Intel hardware (at least on my Sandy
Bridge HD3000 system). Still, I prefer minor graphic glitches over a unusable
desktop, but then, things used to work just nicely, so...
While this seems to be a common bug that was fixed upstream months ago (from
what I've found on a quick search, it was a Mesa bug), I am not getting either
DRM errors from i965 on dmesg, or other OpenGL-related woes (everything else
seems to work just fine, from glxgears up to heavy 3D games)
