We have recently migrated from CentOS6/Gnome to CentOS7/Mate - and have noticed 'glitches' with some Qt applications that appears to be linked to the 'org.mate.Marco.general' 'compositing-manager' setting - and wondered how we 'fix' the issue ...
I tested with one environment where I have two VMs under oVirt 4.2 and I connect to them using remote-viewer and spice in full screen mode. One is a fully updated CentOS 7 VM One is a (not fully up to date) Fedora 28 VM
Both using Mate as DE. On CentOS 7 Mate 1.16.2. On F28 1.20.1 I confirm on both the setting is true and I never tricked with it, so it should be the default.
Below is a PyQT4 python script that shows the issues:
- With 'compositing-manager' set to 'true' (I believe the default
setting):
gsettings set org.mate.Marco.general compositing-manager true
Running the script and the window background is transparent - which is fine
However, if the pull down menu is selected and the 'Toggle' button pressed, the menu stays on the screen - and stays put even if the window is moved
I confirm exactly your behaviour with CentOS 7. The toggle makes the drop down to remain expanded and if I move the window the drop down remains where it was. With F28 all is ok and as expected
- With 'compositing-manager' set to 'false' :
gsettings set org.mate.Marco.general compositing-manager false
Running the script and the window background is no longer transparent - which is not good, but the pull down menu issue is fine ...
I confirm no transaprent background on both and correct behaviour on both
Using CentOS7/Gnome3 works as expected (transparent background and pull down menu is fine)
Not tried this
Anyone have any idea what the problem(s) might be and how to fix it/them ?
