Display scaling of my Steam Deck not sticking after logging in from gamemode

[RodoMa92]

Describe the bug

On current version of bazzite 41, the display scale of the integrated panel seems to keep resetting each time once switching to desktop. It's not a problem with the stock panel, but it makes it unusable with higher resolution displays.

What did you expect to happen?

Once I log it in KDE desktop, my display scaling remains correctly set at 150% on the integrated panel, which it does not. I can see that the loading logo scales back a couple of seconds after booting up, so something during login is forcing the scale back to 100% instead of my setting. This do not seem to happen to external monitors, so I have no clue where the problem stems.
