GTK themes doesn't work correctly after Plasma 5.20 upgrade (Manjaro testing)

It can be noticed in case of pamac. If the new GTK theme is applied, all looks fine: [Screenshot_20201015_184036] But after the session is relogged or system restarted, the window buttons are missing: [Screenshot_20201015_183729] They are there and I can close the window, clicking the empty space blindly, but the issue persists with every GTK theme I tried so far.
