Since the new release built using Qt6 Telegram Desktop ignore any icon settings theme specified in xfconf:
* channel: xsettings
* property: /Net/IconThemeName

Also, opening Teelgram Desktop from the terminal throws several erros about svg:

qt.svg: Error while inflating gzip file: SVG format check failed
qt.svg: Error while inflating gzip file: SVG format check failed

I tested the official Telegram Desktop build and doesn't have the bug, and it doesn't throw the error messages either, so maybe the build needs to be done with other flags.

Checking the problem further, I found that my previous comment is a mistake and there's no bug.

In the past builds, the icon theme was applied because I set the env variable 'QT_QPA_PLATFORMTHEME' to 'gnome' but recently, the wiki was updated (Dec 30th) with extra information for qt6. So now, by installing the qt6ct package and setting the env var to 'qt6ct', I'm able to edit the style of qt6 apps.

I will close the issue and I will try to provide more information into the wiki if it was necessary at some point.
