The font size and UI components are too big for some applications, such as VirtualBox and Krita. I can fix this on a per-application basis by changing the "high DPI settings" under the Context Menu>Properties>Compatibility tab for the shortcut, but I don't want to have to change this setting for each and every application affected. This has only started happening recently, and I don't remember making any substantial hardware or software changes.
"Settings>System>Display>Change the size of text, apps, and other items" is set to 100% - changing it to something else and back doesn't fix the issue. "Advanced scaling settings" is not set.
VirtualBox - font too big
VirtualBox - correct font
Krita - font too big
Krita - correct font
