GNOME Bugzilla – Bug 318550
skip_taskbar_hint interfers with tooltips
Last modified: 2018-02-10 03:46:00 UTC
Version details: Runtime: gtk+-2.6 Distribution/Version: XP 1. compile and run the attached exploit. 2. move window 2 such that it is in front of and overlaps with window 1. 3. move the mouse pointer over the "Wait for my tooltip" label and wait until the tooltips window appears. On my system, this changes the stacking order of the windows such that window 2 is now behind window 1. When commenting out the line gtk_window_set_skip_taskbar_hint(GTK_WINDOW(window1), TRUE); it works without problems. Does not happen on Linux/X11.
Created attachment 53321 [details] Exploit for reproducing the bug
Thanks for reporting this, and especially thanks for attaching a sample program. The problem still exists in the current stable branch, 2.8.
In 2.10.x, removing gtk_window_set_skip_taskbar_hint() no longer help. Probably because gtk_window_set_skip_taskbar_hint() is called somewhere inside GTK+.
We're moving to gitlab! As part of this move, we are closing bugs that haven't seen activity in more than 5 years. If this issue is still imporant to you and still relevant with GTK+ 3.22 or master, please consider creating a gitlab issue for it.
