            Bug ID: 506138
           Summary: frequent display corruption when hovering or scrolling
                    through elements (panel, windows)
    Classification: I don't know
           Product: kde
      Version First unspecified
       Reported In:
          Platform: Fedora RPMs
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: michail.tsouk at gmail.com
  Target Milestone: ---

SUMMARY
The cursor duplicates at a 2-3cm offset horizontally and the screen below it
corrupts at seemingly random points (corruption looks like full screen width,
single color or striped area). Moving the mouse clears the corruption.
Sometimes the corruption appears when selecting textboxes and the blinking
cursor appears; Corruption appears and disappears synchronised with cursor
blinking, until mouse is moved then corruption does not appear.

STEPS TO REPRODUCE
1. Open a text area (Kwrite, or web text box)
2. Alternate focus between the text area and some other element to trigger the
corruption; bug more reliably appears with the mouse being static after
focusing.
3. Bug can also appear in other contexts, such as scrolling through the system
settings list or application launcher entries, or hovering over panel entries.

OBSERVED RESULT
pointer duplicates, full screen width diplay corruption south of the pointer

EXPECTED RESULT
corruption does not appear
