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@lists.freedesktop.org ReportedBy: eugene.shalygin@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.
Back trace of kwin:
