Hi there,

I'm new to Linux so the solution to my question might be obvious. Currently I'm on a dual boot system with KDE neon and KDE Plasma v5.19.80, and on the other side is debian buster 10.4 with GNOME 3.36.3 installed.

I prefer KDE Plasma but I don't like the poor appearance of GTK based applications under Plasma. For example GParted looks fine in GNOME, but not good in KDE Plasma with it's resembled Qt theme. Is there any way to enable the original look of GTK apps under KDE Plasma? Maybe install GTK libraries and GTK icon packs or something else?

Click on Breeze theme in system settings change these:
