i'm on Ubuntustudio 20.4 and i'm using grsync to backup my data. This was working fine since I installed Ubuntu, but now grsync takes over 30s to start. I tried via the terminal and from the start menu with the same long loading time. I installed appmenu-gtk2-module as suggested here:

but there's no improvement. Also Chromium is starting quite slowly when starting it the first time after a boot. When starting it a second time it comes up fast. However Grsync starts always slow and this problem started maybe some weeks ago (was not using grsync for some time). I figured out that it basically affects all QT apps.
My distro:
Distributor ID: Ubuntu Description: Ubuntu 20.04.1 LTS Release: 20.04 Codename: focal
with XFCE. Does this also affect other users? If so, I likely have to wait until the bug is fixed.
