I assume you use KScreen, right? which git commit do you use for kde-workspace? @Thomas: did you already merge the one commit? Would it fix this issue?
no & yes. sorry for the delay.
That's the version I have compiled: d0c465841a7938f4cabc81f8dc66d68dc64b4cac
You don't assume I use KScreen, I said it in #0 ;) I do use KScreen
KScreen doesn't really matter - i can trigger that by an xrandr shortcut. You need https://git.reviewboard.kde.org/r/110385/ - i'll push it tonight.
Git commit 94f501fbfa070293c051b40934681d3b0d902a94 by Thomas Lübking. Committed on 10/05/2013 at 22:03. Pushed by luebking into branch 'master'. connect toplevel to in-loop screenCount() signal required because Screens::changed is emitted queued in case of timer shortcut since a direct signal would cause problems on screen resizes (or rotations, for that matter) since at that time QDesktopWidget::screenGeometry(int) -xrandr- is updated, but QDesktopWidget::screen(int)->geometry() (root window) is NOT, resulting in an invalid value in geometry.cpp/Workspace::desktopResiized(), thus a "capped" overlay window However, w/o the count updated we re-encounter what RR 110119 was supposed to fixed in the first place ...
