--- Comment #4 from denis bonnenfant denis.bonnenfant@diderot.org 2011-01-18 03:46:33 CST --- This bug is not a performance issue : setting a high debug level (+gdi,+x11drv) slows down all the application, but the bug remains, and left panel refresh behaves exactly the same : collapsable area title disappears slowly, left to right. After that, title areas are unclickable. So my guess is that some refresh are done with uninitialized values, leading blank text and unclickable areas. Logs shows that all the operations are done in the same thread.
Is there particular debug channels to trace for this kind of problem ? Or a specific procedure for live debugging ?
