package konqueror submitter 214475 ! reassign 214475 xlibs thanks Hi,
I have found out more information about this bug. As a previous poster already said, it occurs only in the KonqSideBarDirTree, the sidebar that appears when pressing f9. It occurs when some I/O or other kind of hard work has to happen after switching from one directory to another. Also, you have to try to move your mouse as fast as possible away after clicking, this was also mentionned before. For example, if one directory is shown in a different konqueror view mode ( list view vs. icons ), then after switching from the list view to the icons, a lot of work has to happen ( i guess loading the library from disk ? ). While this work is being done, no X input is being processed. Next, when control returns to the Qt event loop, it apparently gets first a pretty big mouse movement and only then the release event ( I've debugged it with a breakpoint on QApplication::x11ProcessEvent and such ). Apparently, this is a bug in Xlib. On merging two subsequent mouse move events, it apparently does not check whether a mouse release occurred in between them ( in which case it should of course *not* merge them ). I'm setting the submitter to myself ( as I can reproduce and comfortably debug it ) and reassigning to Xlibs. cheers domi
