[tde-users] GTK 3 TQt Engine Styles

I use a GTK 3 application ("Revolt" on Debian/Devuan) and its titlebar is so ugly. I tried to use my TDE style for it in "GTK Styles and Fonts" and it only makes it worse. GTK 2 applications look much nicer with Tqt3 integration, but GTK 3... It's an eyesore no matter what, to say the least. This brings me to my question - is there any way to make GTK 3 apps integrate more nicely into TDE? I have gtk3-tqt-engine-trinity installed but there's only the default style available or use my TDE theme for it (which breaks it and makes it look worse).
