Changing a color scheme sets the dpi scaling to 100% in newly open programs. Setting it to something else and reapplying or relogging fixes the issue. Having accent color set from wallpaper and background set as a slide-show will reset the scaling every time the wallpaper changes, making using those 2 things together a nuissance on HiDPI screens. STEPS TO REPRODUCE 1. Have scaling set to something else than 100% 1. Change color scheme SOFTWARE/OS VERSIONS Linux/KDE Plasma: Void Linux, Plasma 5.25.3 KDE Frameworks Version: 5.96.0 Qt Version: 5.15.5 ADDITIONAL INFORMATION The issue didn't appear originally, doing something in the settings made it start happening, I'm uncertain what but I didn't do anything unordinary (Only changed the wallpaper, scaling, played with breeze window decoration settings, didn't originally install any additional window decorations)

That's odd. Some questions: 1. Are you manually setting your font DPI to anything non-default? 2. Does it happen on Wayland, or only X11?
(In reply to Nate Graham from comment #2) > That's odd. Some questions: > 1. Are you manually setting your font DPI to anything non-default? Nope, I only changed the scaling through the option in display settings. I believe I ticked it off and on though which is what could've been the thing that made it start happening, I didn't touch it afterwards and I left it to be controlled by display settings' scaling option > 2. Does it happen on Wayland, or only X11? I only tried X11, can't really run wayland currently
Any chance you can grit your teeth and try Wayland to see if it happens there?
both colours and text go via xrdb; we're presumably overwriting instead of merging into the DB on wayland it might affect newly spawned xwayland apps but not others as there font dpi overrides are an env var

More info I am able to give about this issue: -Also seems to happen cursor is changed -I wasn't able to test it in a wayland session (a frame every 3-5 seconds), but that seems to start with the default 1.0x scaling, so I guess it's related to xrdb
This also seems to happen when changing a gtk theme, though in this instance I remember it happening on clean install as well

Ok i'll summerise what I know, the issue seems to appear when: -changing a color scheme -changing a cursor -changing a gtk theme -basically, whenever a gtk theme is updated I wish I could test it on wayland but again, not possible for me, sorry. Hope that helps though.
I was able to replicate it on a fresh install but I'm really unsure what made it happen in the first place, it doesn't seem it be one thing in particular since I tried checking stuff one by one and it didn't start happening until I started changing application/aurorae theme which wasn't even the case in the original post and didn't happen the first time I did it either. I'll try clicking around in a virtual machine until I'm able to 100% make it reproducible, but so far not so good
Can't reproduce on the plasma 5.25.5, closing the issue since it probably has been fixed.
*** Bug 465166 has been marked as a duplicate of this bug. ***
Can't repro on Plasma 6 X11 or wayland. Closing as fixed.
