Dear Maintainer,

I have two ARM64 tablet device both with Debian bookworm on.
On device 1 the tray icon for cmst scales correctly.
Device 1: dpkg -l |grep cmst
ii  cmst                                  2019.01.13-1+b1                    arm64        QT GUI for Connman with system tray icon
On device 2 the tray icon is smaller than it should be and the space that the icon should be filling, but isn't, is filled with digital noise.
Device 2: dpkg -l |grep cmst
ii  cmst                                          2022.05.01-1                       arm64        QT GUI for Connman with system tray icon
Both devices have high res screens and so to make the touch interface usable I have done two things:-
1. set the environment variable QT_SCALE_FACTOR to 2
2. increased the height of the "panel" and "icon size" that applies to the task bar.
I am not sure which of these things has caused the scaling that cmst is not picking up.
