See the attached video. It works fine with kwin and metacity.

Monodevelop 2.8.2 works fine in the same setup.
Comment 3 Nikita Tsukanov 2012-02-21 09:42:28 UTC
As I can see this issue is caused by this commit: https://github.com/mono/monodevelop/commit/a5524bf142e4119cab05e132bf08752dd47e1374
When I compile monodevelop from previos one it works fine.

Actually, I should probably mark the other as a dup of this...

I'm thinking the bug has to be in the DoShowTooltip() in TextEditor.cs because that's the only one that changes the X location.

The other possibility is that getting the location of the window in the DebugValueWindow code is getting invalid values?
Comment 8 Jeffrey Stedfast 2012-02-21 11:22:47 UTC
I can't reproduce this with Ubuntu 11.10 in VirtualBox with the default window manager (how do I even make it use Compiz?)

Can someone who can reproduce this bug add some Console.WriteLine()'s to figure out what is breaking?

I've tried everything and I just can't replicate it.

Marek is helping me debug this with some CWL's in his MD.

Gtk seems to be giving us wrong allocation *and* window position values in the OnSizeALlocated() callback.

It is telling us that the tooltip window is already at 0,0 when it is not, so we adjust the position to a location that is not up against the edge of the screen.
Comment 10 Jeffrey Stedfast 2012-02-21 12:06:11 UTC
Interestingly, Compiz seems to be resizing the tooltip window 5 times ,the third time it just randomly says the window is at 0,0
Comment 11 Jeffrey Stedfast 2012-02-21 12:38:08 UTC
This seems related (windows always show up at 0,0 no matter what): http://bugs.compiz.org/show_bug.cgi?id=5

This one claims Compiz is broken wrt window position reporting (often claiming position being 0,0 when it's not): http://bugs.compiz.org/show_bug.cgi?id=72

Seems very likely to be related.
