My Linux xorg dotfiles/configs. dotfiles-xorg is being merged with dotfiles-wayland!
Customize DPI through General.GreeterEnvironment in etc/sddm.conf.d/kde_settings.conf. For example:
[General]
HaltCommand=/usr/bin/systemctl poweroff
RebootCommand=/usr/bin/systemctl reboot
GreeterEnvironment=QT_SCREEN_SCALE_FACTORS="DVI-I-0=1.25;DVI-I-1=1.25;HDMI-0=1.25;DP-0=1.25;DP-1=1.25;DVI-D-0=1.25;",QT_FONT_DPI=120
Open qt6ct, create a new custom color scheme, edit it, then simply hit Reset palette.
A new color scheme with your correct color choices will magically be made... somehow.
You need to Reset profile every time you make changes to your KDE color scheme though, so the values are synced.
Note that this issue doesn't happen in qt5ct, Qt5 color schemes are still applied correctly.
For Discord, use the discord-electron by SunRed AUR package so screenshare works
