Bug#1005072: mate-tweak: Unpleasant transition from mate-compton to mate-picom

[Mihai Hanor <quake2iasi@gmail.com>]

Package: mate-tweak
Version: 22.04.1-1
Severity: normal
File: /usr/bin/mate-tweak
X-Debbugs-Cc: quake2iasi@gmail.com

Dear Maintainer,

After upgrading the packages and restarting the system (which was configured

with compton as window manager in Mate Tweak), after logging in lightdm, all

the windows were missing their decorations and normal window controls, while

window management was impossible.

** To fix it, start MATE Tweak and select another window manager (current selection

is shown as empty).

** Excerpts taken from .xsession-errors:

x-session-manager[1897]: WARNING: Unable to find provider 'marco-compton' of required component 'windowmanager'

(mate-settings-daemon:2063): Gtk-WARNING **: 20:55:39.286: gtk_widget_size_allocate(): attempt to allocate widget with width -1 and height 27
Window Manager is: Unknown
