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: > > 1.

[CentOS] CentOS7/Mate Qt bugs/features?
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 ...
Below is a PyQT4 python script that shows the issues:
1. 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
2. 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 ...
We're using Nvidia cards with the Nvidia drivers - but I can also
reproduce the issue on a Vmware player instance
It would be good to know if anyone else can reproduce this with Mate ?
Using CentOS7/Gnome3 works as expected (transparent background and pull
down menu is fine)
Anyone have any idea what the problem(s) might be and how to fix it/them ?
Thanks
