            Bug ID: 93879
           Summary: kernel 4.4.0 causes application lockup and unusable
                    interfaces with radeon hardware
           Product: DRI
           Version: XOrg git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: critical
          Priority: medium
         Component: DRM/Radeon
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: jimmy@boombatower.com

While running Plasma 5 on 4.4.0 the following occurs periodically:
- chromium locks up
- plasma desktop locks up
- unable to enter password on plasma lock screen

A trigger for locking chromium up seems to be to resize the window by dragging
to screen edges (top to fullscreen, left to tack up left half of screen, etc).
Otherwise, it also seems to somewhat randomly freeze over time.

Reverting to 4.3.x resolves the issues.
