            Bug ID: 91153
           Summary: Intel SNA: bright pixels appear when mousing over
                    LibreOffice Impress
           Product: xorg
           Version: unspecified
          Hardware: Other
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium

Xorg log file

Running: xf86-video-intel 2.99.917-5 in Arch Linux

If I launch LibreOffice with a couple of dark-background terminal windows on
the screen, select the "Impress" application (clone of powerpoint), bring the
terminal windows forward, and move my mouse around a bit (hitting areas of the
LibreOffice window), bright pixels appear in my dark terminal windows.

This only happens when using "SNA" mode in the intel driver.

This is on a ThinkPad T430s.
I can reproduce this very easily. It does not happen in UXA.

I've attached an Xorg.0.log file. I'll attach a screenshot showing some bright
pixels in the term windows in the next entry. Let me know if I can provide any
other files.
