           Summary: [RADEON:KMS:R600G] kwin freezes at drawing combo boxes
           Product: Mesa
           Version: git
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/r600
        AssignedTo: dri-devel at lists.freedesktop.org
        ReportedBy: eugene.shalygin at gmail.com


Time to time kwin freezes when I click on combo box. Most offen it occurs in
Konqueror, but in Firefox also. I believe that it happens more offen when I
click on combo box when page continues to load (i.e. render). It started from
KWin 4.6.0.
