I have this issue too. I doubt it's gfx driver related as this: - only happens to evolution - only happens to the preview pane (but not when opening the same message in a new window with double click) - there are no driver related errors in the system logs; And the system works just fine after this error occurs. - HOWEVER, when the error happens, the .xsession-errors log file gets flooded with errors like :
