@hj honestly i think qt looks bad everywhere, no matter how much you theme it. gtk with a good theme can look good on almost any linux desktop, but it looks weird on window managers
Qt doesnt try to look native on Linux. They have removed the GTK2 theme support completely and never cared enough for a GTK3 (or 4 by now) replacement. The #fedora community managed to create an adwaita-qt style https://github.com/FedoraQt/adwaita-qt that works pretty well, but Qt itself doesn't care about the Linux desktop anymore.
On macOS Big Sur Qt looks really bad, on Windows 10, by now Qt also looks dated, except you do something like Telegram, where you ship your own design.
@riku yeah, don't run it on xwayland mode, but native.
There are times when it's fine and other times where you barely can scroll or where it shoots you from one end to the other.
