Idea Linux fonts antialiasing ruined

Hello, yesterday my fonts antialliasing both in Idea and Android studio became ruined. I tried to fix it with next steps:

Added settings to studio64.vmoptions in Android studio and Idea:

-Dawt.useSystemAAFontSettings=on
-Dswing.aatext=true
-Dsun.java2d.xrender=true

Changed runtime like there https://intellij-support.jetbrains.com/hc/en-us/articles/206544879

Nothing helped. OpenSuse Leap 15.1. Yesterday update was big including GTK theming and fonts update.
