Hello, this is something very annoying I'm hitting with KDE 4.9 on 3 different systems of mine. If you want to move a window or unmaximize it and then muve it, there is a (big) delay until it starts to move the window if you try to select the upper side of the tittle bar. If you select the lower part of the tittle bar - it works fast as expected. Reproducible: Always Steps to Reproduce: 1. Open for example dolphin 2. Try dragging the tittlebar of the window with the mouse (preferibly on the upper side of the tittlebar) 3. You should notice a big delay I've uploaded a (very) short (unlisted) video on youtube (link here: http://www.youtube.com/watch?v=gXBb5wV6dFs ) that shows exactly the behaviour I'm trying to explain. I've tried 5 different themes and the same bad behaviour is noticed. Regards.
After a couple of more tests, it seems there's no such a problem if using the default Oxygen window decoration. Any other window decorations present the problem described above.
Hi, I'm writing to confirm this bug, and its repreducability. When using KDE 4.9 and using any window decorations that use transparency, if you attempt to use the window's titlebar to move any given window, the window will lag in place for a few seconds, then jump to your cursor. This makes it very difficult to use, as the lag is at least a couple seconds before the window starts to move and the positioning of the window after the lag is a bit unpredicable. I tested a bunch of different windows decorations and any decoration with transparency seems to cause the issue, the default ones, like Oxygen, are fine. I should add that when you drag a window by its pane (in places where this is possible), instead of the titlebar, there is no lag when moving the window.
