Qt apps don't scale properly on fedora 36

I am using font scaling factor on gnome-tweaks to scale.
I tried installing qt5ct and adding export QT_QPA_PLATFORMTHEME="qt5ct" to my .profile but that didn’t work.

I then tried removing qt5ct and added this to my .profile:

export QT_AUTO_SCREEN_SCALE_FACTOR=0
export QT_SCALE_FACTOR=1.3

from this link : HiDPI - ArchWiki
After that, the apps still look weird:

See here that that in qbittorrent the cross icon has dissappeared. It has gone out of the screen to the right.

The issue does not happen if I install qbittorrent as a snap:

I would rather have it installed as rpm from official repositories though, so I’d really appreciate it if anyone has a fix.

Is there no fix for this? Maybe it’s just about how those apps are packaged for fedora?
This issue doesn’t happen on debian and ubuntu and even arch.

removed qgnomeplatform-qt6 and that fixed this. Remove qgnomeplatform-qt5 too if some QT apps continue to have the issue.
