KDE is in better shape than GNOME, but there are still some nits. Nearly all the available third party themes for example are blurry or otherwise render incorrectly with fractional scaling on.
Problem is, the stock themes aren't to my taste at all.
To my understanding, doing that wouldn't be helpful due to hard technical limits that can't be reconciled. Most window chrome themes are Aurora themes, which don't play nice with HiDPI, and to change that they'd need to be rewritten as C++ themes (like the default Breeze theme is), which is beyond the capabilities of most people publishing themes.
So don't use a third party theme.
