Description Elias Probst 2012-12-21 15:12:15 UTC

Using KDE 4.9.95 (4.10 RC1), Qt 4.8.4.

When moving a maximized window, it is positioned outside the cursors focus.
The window should be positioned below the cursor.

See the video in the bug URL for a short demonstration.

This behaviour might be related to the fact, that I recently had a 2nd display connected to my laptop (X was not restarted since then, only kwin).

We've had such, but it does not occur here (atm) - i'm not sure whether it's related to multiscreen setups.

It would indicate that the fakeMove is not processed.
Do you have any additional patches or could pot. check whether that call is made (add a qDebug() << "performing fake move";) or inject such debugging patch?

I don't use any additional patches, plain kwin-4.9.95.
Just added a corresponding debug statement to the code and it looks like the fakeMove is not executed. Trying to understand the fakeMove related code now to find out, why it does not happen.

Comment 3 Thomas Lübking 2012-12-23 13:37:53 UTC

please attach the output of "qdbus org.kde.kwin /KWin supportInformation"
fakeMove is only set true in that one location - do you have moveResizeMaximizedWindows enabled (window borders for maximized windows)?

Yes, moveResizeMaximizedWindows is enabled in kwinrc.

Support information is attached.

Comment 5 Martin Flöser 2012-12-23 16:25:56 UTC

random thought: could you try to disable the new Maximize Window effect?

Disable it. While the window simply does not resize at all when dragging it out of quick maximization (and rather should not) the two settings are known to conflict.

Patch to alter everything and resolve that situation unfortunately will not be in 4.10 (and the publically available version is hardly more than poc)

Comment 7 Elias Probst 2012-12-23 21:29:45 UTC

Ok, disabling "moveResizeMaximizedWindows" solved the initial issue.
So I'll just wait for 4.11 and hope the patch to resolve the conflict will be usable by then.

Thanks for your investigations.

Leaving the bug open until the patch is available in master to be tested.
