Description Fushan Wen 2022-08-03 12:52:44 UTC 
SUMMARY
Having the "XWayland apps scale themselves" option seems to make the PLASMA_USE_QT_SCALING environment variable not get evaluated or respected or something. When I set it to 1 and use my X11 session, it's not honored; all the icons are tiny


STEPS TO REPRODUCE
1. Log in to a Wayland session
2. Enable "XWayland apps scale themselves" 
3. Log out and Log in to a X11 session with PLASMA_USE_QT_SCALING in systemd service file or /etc/environment

OBSERVED RESULT
PLASMA_USE_QT_SCALING is not enabled

EXPECTED RESULT
PLASMA_USE_QT_SCALING is enabled

I'm assuming it's 122be66ecc20bcbaa167fd2b8ad03d92f2922e95 in p-w
Comment 2 David Edmundson 2022-08-03 13:23:43 UTC 
Edit, probably not that.

In any case, kwin isn't doing anything on X - it'll be the startup that handles font setup that's changed and wrong.

Comment 4 Nate Graham 2022-09-08 20:11:28 UTC 
It's working for me again now.
