[Solved] Why can't I move or resize my KDevelop window?

I just installed KDevelop (4.5.2 on kde 4.14.3) on a mostly amd64 install with a few ~amd64 packages. All other applications behave fine. KDevelop comes up filling about 2/3 of one of my two monitors, but it seems to think it is maximized, as the maximize, move, and resize menu items are disabled, and there is no restore item. There is a minimize button at the top right, but no restore or maximize button. If I grab the title bar with the mouse and try to drag, I get the four pointed mouse pointer, but the window does not move. There seems to be no border around the window to grab to resize. If it truly thought it were maximized, I would expect a "restore" button or menu, but I can't find one.

I have two monitors connected to a single nVidia card, using the nVidia drivers, but I have no other problems with moving or sizing windows on the single X window spread across the two monitors.

Using Application Specific Settings, I am able to force it off the edge of the screen, so I can now move the window easily, but still no ability to resize.

I'd appreciate any suggestions how to fix this, or where to dig for more information about what the underlying problem is.

Thanks.

You could try `xprop` or `xwininfo` on the window, see if it's forcing those settings in some way. That'd give you a clue on how to override them too.

Seems odd that it'd do that on first run though, have you installed it before? It might be picking up old settings if so.

This is the first time I've installed kdevelop. I'm currently upgrading to 4.6.0-r1 just in case it was a known issue, although I doubt it.

I finally found some useful information. If I ssh in from another box, kdevelop works just fine. The only significant difference in xprop output matches the behavior. (I added the line wrapping just for better visibility.)

I call it "phase of the moon and blue magic dust."

After some googling, trying to figure out where these things might get set, I finally found my way to the Window Manager Settings dialog (from the context menu from right click on the title bar), Window Rules page. There were several entries for kdevelop. I figure some were from my attempts to fix this over the past days, but some may well have been from a forgotten earlier time. I just deleted them all, and now things seem to be working as expected.
