https://bugs.kde.org/show_bug.cgi?id=383410 --- Comment #10 from Roman Gilg --- Thanks for digging into this. You're right that the cursor can't be locked and confined at the same time. The Xwayland code works like this: First confine. If then a certain condition is met

https://bugs.kde.org/show_bug.cgi?id=383410 --- Comment #5 from Roman Gilg --- You're sure it's created only once? While s_osd is a static OnScreenNotification pointer, we still always call create() in osd() and in create() a new OnScreenNotification instance is created with

https://bugs.kde.org/show_bug.cgi?id=383410 --- Comment #3 from Martin Flöser --- I'm not sure whether we actually support locking and confining at the same time, but yeah that's not the problem. It looks like the OSD just doesn't support being shown multiple times. Or in
