This behavior is not entirely deterministic, it occurs about 75% of the times. I have an intel graphic card, and same thing happens no matter sna or uxa is used. This doesn't happen if using kwin_gles instead (but I don't use it because then the blur effect doesn't work). If I then disable the desktop effects, windows and desktop appear normally. If I then reenable the desktop effects, the same buggy behavior happens.

Last, this might be bug #330986, being https://bugs.freedesktop.org/show_bug.cgi?id=74316 try MESA_DEBUG=1 and LIBGL_DEBUG=1 kwin --replace & and watch for errors when windows turn black (if this only

This solved the problem for a while, but now it just happened again. Could this be linked to how linux packages manage to interact with mesa packages? I just got an update on the kernel, but this could be just a coincidence. I'll reinstall mesa to see if it fixes this, and then be watching if this is reproducible in next kernel update... In that case this would most surely be a problem in K-/Ubuntu Also, in kwin_gles it works fine but I get this error, I guess related to why the blur effect is not activated: libEGL warning: failed to create a pipe screen for i965 OpenGL vendor string: Intel Open Source Technology Center OpenGL renderer string: Mesa DRI Intel(R) Sandybridge Mobile OpenGL version string: OpenGL ES 3.0 Mesa 10.1.0-rc1 OpenGL shading language version string: OpenGL ES GLSL ES 3.0 Driver: Intel GPU class: SandyBridge OpenGL version: 3.0 GLSL version: 3.0 Mesa version: 10.1 X server version: 1.15 Linux kernel version: 3.13 Direct rendering: yes Requires strict binding: no GLSL shaders: yes Texture NPOT support: yes Virtual Machine: no kwin(3355): Failed to compile fragment shader: "0:2(14): error: no precision specified this scope for type `vec4' 0:4(13): error: no precision specified this scope for type `float' 0:5(13): error: no precision specified this scope for type `float' 0:6(13): error: no precision specified this scope for type `float' 0:7(13): error: no precision specified this scope for type `float' 0:11(7): error: no precision specified this scope for type `vec4' kwin(3355): Failed to link shader: "error: program lacks a fragment shader Reply at: https://bugs.launchpad.net/ubuntu/+source/kde- workspace/+bug/1283820/comments/15 ------------------------------------------------------------------------ On 2014-03-07T20:32:01+00:00 avlas wrote: Although very weird, this seems to be confirmed by experience.

You could stat the mesa files before and after a kernel update to see whether they've been compromised. Just to rule that out: "updated linux" includes a reboot, yesno?
