Perhaps its a product of my configs but windows seem to behave strangely in KWin. Clicking anywhere in the title bar produces a diagonal drag handle which sometimes
behaves as a drag handle and other times as a standard cursor. Windows also seem to unmaximize randomly, though clicking on Maximize will actually minimize the window.
Is this just me (perhaps a misbehaving theme) or is anyone else seeing this?
UPDATE: After a bit more testing, it looks like this issue only occurs when many windows are open. Perhaps an issue in KWin with focus switching (I haven't torn into the source yet)?
