Created attachment 110134 [details] screenshot I use 1.2 as display scale under X11 session in plasma 5.12 beta, Arch Linux. right click sound icon in system tray, open "audio volume settings" select "audio volume" section on left side My screenshot shows the big radio button
Does it also happen with Fusion style? plasmashell -style fusion
I just noticed that the problem happens even when I use default display scale. Fusion style is not applied to the radio buttons shown in my screenshot even after I restart plasma session. "system settings > multimedia > audio volume" shows radio buttons in fusion style and their size is correct here when I use both breeze/fusion styles.
