Font scaling in 2020.7

Postby eprst » Sat Aug 08, 2020 1:01 am

I have a mixed DPI setup with 4K screen on my laptop and a "regular" DPI external monitor. My Linux/KDE is configured with ~170% font scaling so that things don't look too tiny on the laptop screen, and I scale fonts down in IDE/Browser etc if I move them to the external monitor.

YourKit used to respect `yk.font.scale` settings but not anymore, everything is huge with my setup. Any workaround?

1. Please try disable HiDPI scaling by adding "-Dsun.java2d.uiScale.enabled=false" to startup parameters.

2. Custom font size can be set with "yk.font.size" integer property.

"-Dsun.java2d.uiScale.enabled=false" makes it more usable, but "yk.font.size" has no effect

In addition to "yk.font.size" please also specify "yk.font.name".

You can find the font name in the profiler UI log file <user home>/.yjp/log/profiler-ui-<pid>.log. Search for the line with text "Primary font" to look up the font name.
