I've also been able to recreate this issue while running cairo-dock on a Clevo P150EM (Intel HD4000).
I see the status is NEEDINFO. I've worked around the issue for myself by just using the cairo back end, but is there any info/testing I can provide to help resolve the issue when using OpenGL? evil@clevo:~$ lsmod|grep "^i" ... i915 610430 4 ... evil@clevo:~$ sudo lshw -C display [sudo] password for evil: *-display description: VGA compatible controller product: 3rd Gen Core processor Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 09 width: 64 bits clock: 33MHz capabilities: msi pm vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:45 memory:f7400000-f77fffff memory:d0000000-dfffffff ioport:f000(size=64) evil@clevo:~$ glxinfo | grep OpenGL OpenGL vendor string: Intel Open Source Technology Center OpenGL renderer string: Mesa DRI Intel(R) Ivybridge Mobile OpenGL core profile version string: 3.1 (Core Profile) Mesa 9.1.4 OpenGL core profile shading language version string: 1.40 OpenGL core profile context flags: (none) OpenGL core profile extensions: OpenGL version string: 3.0 Mesa 9.1.4 OpenGL shading language version string: 1.30 OpenGL context flags: (none) OpenGL extensions: -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1180646 Title: cairo-dock rendering issues using openGL backend on intel GPU To manage notifications about this bug go to: https://bugs.launchpad.net/mesa/+bug/1180646/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
