            Bug ID: 380008
           Summary: System randomly freezes or crashes to the login
                    screen, glitches until rebooted
           Product: frameworks-plasma
           Version: unspecified
          Platform: Other
                OS: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: NOR
         Component: libplasma
          Assignee: [email protected]
          Reporter: [email protected]
  Target Milestone: ---

Approximately once every 1 to 3 days of uptime, the system experiences a sudden
and inexplicable crash: The image completely freezes in place, although unlike
similar crashes in the past I can keep moving the mouse pointer around. A few
seconds afterward, I find myself in a black console... and a few seconds after
that, I'm back at the login screen. If I attempt to log back in however, the
image either freezes again or desktop effects are no longer working without any
error message as to why. Not even forcefully restarting X11 (control + alt +
backspace twice) fixes the remaining glitches, and the only way to truly
recover the system is to also reboot.

The crashes are completely random, but always caused by a desktop event...
however it is not exclusive to desktop effects! The freeze will occur even with
compositing completely disabled, although slightly more rarely. It seems to
occur either when some desktop effects are playing (like the desktop switching
cube animation) but it's usually when I select a new window or a panel pops up
(alt-tab switching to another window can alone trigger this).

I use the free video drivers and default system packages, all latest versions
of openSUSE Tumbleweed. My card is a Radeon R7 370, GCN 1.0 on RadeonSI.
