Created attachment 1107938 [details] Screenshot of bug Description of problem: Version-Release number of selected component (if applicable): Fedora 22/Cinnamon 2.6.13 and Fedora 23/Cinnamon 2.8.6 (& probably others) Steps to Reproduce: 1. Open Firefox - click to show the drop-down list for the search bar 2. Move the Firefox window - click to show the drop-down list for the search bar Drop-down list appears in correct place 3. Again click to show the drop-down list for the search bar Drop-down list appears in the position relating to the original Firefox window placement Additional info: This appears to be a Cinnamon bug specific to the Fedora implementation. The Fedora/Cinnamon versions shown above are on computers that also have other desktops installed (Gnome, Gnome Classic) and these other desktops do not show this bug. Nor does the bug show under Mint (Mint 17.3, Cinnamon 2.8.6). Nor does the Firefox version seem to matter - and the bug shows whether the search-bar is the old interface (one search provider per line) or the new (search providers as icon grid). See attachment for example of bug. Note the tool-tip by the cursor and the corresponding highlighted icon on the misplaced grid.
fedora firefox uses gtk3 (mint uses gtk2)
(In reply to leigh scott from comment #1) > fedora firefox uses gtk3 (mint uses gtk2) Hi Leigh First of all, thanks for all your work on Fedora Cinnamon - I really appreciate it as it's my main OS/desktop. I take your point about Fedora Firefox using gtk3. However, if it's a Firefox bug, why don't Gnome and Gnome Classic show these bugs? Both of my machines showing this bug have multiple desktops installed (Cinnamon, Gnome, Gnome Classic) and it's only Firefox under Cinnamon that shows the bug. Obviously, Firefox under these other desktops is using gtk3 - what gives?
That is: https://bugzilla.redhat.com/show_bug.cgi?id=1281817 https://bugzilla.mozilla.org/show_bug.cgi?id=1022241#c26 There's a simple fix for that - ensure that Cinamon does not send configure notification signal to hidden windows (which is pointless anyway).
Moving back to cinnamon. If you don't want fix that on cinnamon side feel free to close/dupe it.
Cinnamon 3 has fixed this bug. :-)
