--- Comment #14 from Jan-Marek Glogowski <glo...@fbihome.de> --- So this time I can confirm, that "Alt + Shift + F12" stops the compositing and the flickering. Guess I hit the wrong key combo last time, or I had a different problem, but xsession-errors and dmesg show almost the same messages: Today: [18199.442243] radeon 0000:01:00.0: r600_check_texture_resource:1566 tex pitch (888, 0x40, 1) invalid [18199.442334] [drm:radeon_cs_ioctl [radeon]] *ERROR* Invalid command stream ! Previous: [26610.825302] radeon 0000:01:00.0: r600_check_texture_resource:1566 tex pitch (792, 0x40, 1) invalid [26610.825349] [drm:radeon_cs_ioctl [radeon]] *ERROR* Invalid command stream ! What's the preferred way to set a different QT_MESSAGE_PATTERN? Edit startkde? Guess the example from the Qt docs is ok for you: QT_MESSAGE_PATTERN="[%{type}] %{appname} (%{file}:%{line}) - %{message}" This proves my theory about the "late at day" is wrong, as I neither installed new software, nor intensively used the system. Actually this time it happened almost instantly after the first start of LO, when opening a dialog. -- You are receiving this mail because: You are watching all bug changes.
