Screenshot showing the issue

Version:           git master (using Devel) 
OS:                Linux

Setups in which the issue appears:

1. 2 x 1280x1024 monitors, primary on right, secondary on left
2. 1 x 1680x900 screen, rotated 90 degrees and 1 x 1920x1200 screen, primary

In both cases, right clicking on the window decoration to bring up the menu when on the right screen causes the context menu to appear on the left screen (see attached screenshot). 

Reproducible: Always

Steps to Reproduce:
1. Open a window on the right screen
2. Right click on decoration

Actual Results:  
Menu appears on the left screen

Expected Results:  
Menu appears where the mouse pointer is

This is on recent git master, and this has been observed with two different Radeon cards, running kernel 3.1 rc10 and Mesa 7.11.
Comment 1 Martin Flöser 2011-10-23 20:19:31 UTC 
I cannot reproduce here and I am pretty sure the window gets positioned by Qt.
Comment 2 Luca Beltrame 2011-10-23 20:20:31 UTC 
That may be a hint: I'm running a recent snapshot of Qt 4.8, so possibly a Qt bug?
Comment 3 Martin Flöser 2011-10-23 20:26:01 UTC 
could be. I'm still on Qt 4.7. Any chance to verify with Qt 4.7?
Comment 4 Luca Beltrame 2011-10-23 20:27:57 UTC 
Not at the moment, unfortunately, as the way I update KDE is tied to the Qt version I get.

As mentioned in bug 284876, this is also a problem on single-monitor systems.  It's just really pronounced on a dual-monitor setup since the menu appears really far away (on the left) from a window on the right-monitor.

Fedora 16 Beta is currently shipping KDE 4.7.2 with qt-4.8.0-0.17.rc1.fc16.x86_64.

It's also interesting that the menu placement is relative to the cursor position when you right-click on the title bar.  That is, if you right-click near the left edge of the title-bar, the menu appears next to the left-edge of the monitor.  But if you right-click in the middle of the title-bar, say 100 pixels from the edge, the menu appears 100 pixels from the left-edge of the monitor.

It's likely still this one then: http://old.nabble.com/Problem-with-QWidget->mapToGlobal()-td32137926.html
Comment 8 Jeffrey Bastian 2011-10-25 21:29:18 UTC 
Alt-F3 does bring up the window menu in the right spot.
Comment 9 Martin Flöser 2011-12-10 08:46:25 UTC 
currently fixed in Qt.
