If I switch to workspace with Chromium in fullscreen mode I see xfce-panel overlapping Chromium. To hide panel I need too turn fullscreen mode off and then turn it on again. P.S. I think this bug is reproducable for all non-decorated windows because if I set Chromium to use system frames and title bar all works great.
Works for me in 4.10
Happens with 4.10 as well (on Arch Linux), but only if the Chromium window is maximized before going to fullscreen. This bug might also be related: https://bugs.archlinux.org/task/28450.
Also reproducible on Xubuntu 12.04, if that helps further investigating the issue.
Created attachment 4777 Testcase Issue is still present in 4.10. Attached testcase (from Arch bug report) still reproduces the issue for me (xfwm 4.10, Qt 4.8). Run xfwm_qt.py, ensure window is maximized (M), switch to fullscreen (F), toggle menu bar visibily (H) -> xfce-panel is drawn on top of the supposed-to-be-fullscreen window.
Created attachment 4960 Fix I hope this patch fixes an issue. (Makes Fullscreen flag override Maximized)
This bug is still present in 4.10.1 although the patch has been available for weeks. It doesn't seem to affect newer versions of Chromium, but Qt apps (e.g. VLC) are still affected. I have been using the patch for some weeks without any issues. (Thank you, Viktor Semykin.) It would be great if it was included in future versions.
Confirming and requesting inclusion of patch. Details of my confirmation here: http://forum.xfce.org/viewtopic.php?id=7682
I also confirm this bug affecting VLC(2.0.8) and Xfce(4.10) on Arch Linux. Please apply the patch.
I can confirm that patch fixes this behavior with a Qt based application (MythTV) in Ubuntu 14.04 development.
