QT_AUTO_SCREEN_SCALE_FACTOR has been deprecated in >=Qt Gui 5.14

[ahjolinna]

https://wiki.qt.io/New_Features_in_Qt_5.14

Added the QT_ENABLE_HIGHDPI_SCALING environment variable which enables high-dpi scaling based on display DPI. Replaces QT_AUTO_SCREEN_SCALE_FACTOR (now deprecated), and corresponds to the Qt::AA_EnableHighDpiScaling application attribute.

havent checked if this affects qml also yet, but just in case

Is this why Orion crashes when it tries to resize/add new stuff in the UI?

[ahjolinna]

works for me on arch and openSUSE, have you tried a rebuild?

[neurodiverseEsoteric]

Will try to see if a rebuild fixes that, but before it wouldn't always crash after left-button-pressing over a followed channel icon
