Originally submitted to KDE: https://bugs.kde.org/show_bug.cgi?id=390116 It was suggested that it was an x-server issue.
The short of it is this... If my system is under heavy load and I try to drag a window such as chrome, the window starts off by changing into transparent drag-mode and is slow to start to drag and at some point I think loses my mouse and remains in that transparent-drag mode. At this point I'm no longer able to click on anything, but rendering still works fine in this state. The keyboard seems to work "somewhat" as well... While I'm unable to alt-tab or alt-f4 I think, I am able to CTRL-Shift-ESC and switch tty. Once I force the offending program to quit (not xorg stuff, but the window I was dragging), everything goes back to normal. I suggested that maybe periodically poll the mouse state instead of relying on an interrupt/event that may not be caught in cases like this. _______________________________________________ firstname.lastname@example.org: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: https://lists.x.org/mailman/listinfo/xorg Your subscription address: %(user_address)s
