Intellij Idea and Android studio fonts antialiasing ruined after Leap 15.1 update (24.05.2020)

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:


Changed runtime like there
Nothing helped. Yesterday update was big including GTK theming and fonts. (gtk3-metatheme-adwaita, gnome-themes-accessibility, libfreetype6 etc.)

P.S. First time I made a rollback via Yast’s Filesystem snapshots, it helped to return antialliasing back. But after that I updated my system again and can’t restore.

Thanks! It looks like, a new update quickly needed.
