Telegram Icon in Tray is Blank

User Support General
1

Qubes 4.2, Xfce. New VMs and some old VMs (50%/50%) are affected by this bug. Tray icon images are blank (see attach). I guess it is after installing KDE (I saw blank icons in menu of installed kde applications. Go Menu > settings > other). I already deleted kde and rebooted but didnt help.

The weirdest thing that this happens on identical vms. There is NO difference between vms. But on one tray icon shows correctly, and on other - blank.

But. If I clone vm - the result is the same. If on that vm icon was showing correctly - it will be showing correctly on cloned vm. If it was blank - it will be blank on cloned.

Any ideas?

What is the output of this command (in dom0):

qvm-features dom0 qui-default-trayicon-mode

And the output of this command for correct and faulty qubes:

qvm-features VMNAME qui-trayicon-mode

This is just Telegram bug. If you have enabled “monochrome icon” it will be blank. Unchecking that option fixes the issue.
