Description Fushan Wen 2022-01-29 14:47:45 UTC 
SUMMARY
If I log out from an X11 session (125% scale) and log in to a Wayland session (125% scale), the screen scale is always 100% even if system settings shows 125%. Not sure if it's a bug in Kwin or elsewhere.


STEPS TO REPRODUCE
1. Log out from X11
2. Log in to Wayland

OBSERVED RESULT
100% scale

EXPECTED RESULT
125% scale as shown in system settings

Not likely. The external display has the same name on Wayland and X11, but the bug still exists.

Does it have the same *connector* name too?

If you mean HDMI-A-0, yes. KScreen KCM reports the scale is 125% but the actual scale is 100%.
Comment 6 Nate Graham 2022-06-15 15:25:34 UTC 
OK, then I guess it is a different issue.
Comment 7 Nate Graham 2022-06-15 15:44:21 UTC 
Ah it's actually Bug 433460.
