Version: 4.3.90 (using Devel) Compiler: gcc version 4.4.2 20091222 (Red Hat 4.4.2-20) OS: Linux Installed from: Compiled sources Steps to reproduce: 1. Open Dolphin 2. Snap to left edge 3. Open another instance of Dolphin This works with any program. Expected results: Second instance of dolphin opens at "normal" size. Actual results: Second instance opens "split screen" size. Other notes: The second instance doesn't unsnap either, it has to be resized manually or closed. After the first window is unsnapped new instances go back to opening the proper size. This *may* be considered desired behaviour when opening a second instance and there is only one other, split, window open, but even then it should unsnap correctly. When there are multiple (more than one) windows open, it should definitely open normal size instead of split. It seems to me to be a product of KWin remembering window sizes, which should probably be disabled for snapped windows.
It's the application that's remembering the window size, not KWin. Because of how quick tiling works I can't see a way to fix. - There's no sane way of telling the application that it's quick tiled and we cannot add a way as it will only work for applications that support it. - KWin cannot have the window open up normal size as KWin doesn't know what the normal size was. - KWin cannot mark the window as being quick tiled initially as it still needs to know what the normal size was to restore the window to when the user untiles it.
Well, I don't know the implementation details obviously, but upon further inspection the problem seems to actually only be with KDE apps. Konsole, Dolphin, etc do it and Firefox, Picard, and company don't. Which, yes, indicates that it's not KWin doing the remembering. Do most apps only save/remember their size when closed, while KDE apps always keep track of their current size? The fact that the behaviour seems consistent across all KDE apps indicates to me that this could be a KDE wide issue that could be fixed somewhere within, rather than having to be fixed in each app. But, as usual, I'm just stabbing in the dark. Whatever the cause, I don't think it should be considered desired/proper behaviour. Maybe I can get a second opinion on this part?
KMainWindow could store it's size on close only - otherwise this is just the intended behavior (opens with last applied size, how it got there doesn't matter) There's not much kwin could do (not even guess this was a quick tiled window and unsnap, because we don't know the former size since there was none) and possibly this is no bug at all, but the sheer lack of a brain interface. You can workaround this by either dolphin --geometry 800x400 or applying an initial size rule in "kcmshell4 kwinrules"
