Your QtWidgets apps, such as Dolphin, KMail, Kate etc. can now use the Union CSS files as the source of their styling — first look.

this is especially true for the newer kirigami based apps since kirigami is qtquick and so qtwidgets themes dont look nice with kirigami even though they have developed a bridge to bridge qtwidgets themes with qtquick components called qqc2-desktop-style cuz its incomplete

The secret to making KDE apps look nice outside of Plasma is to set specific env vars that make them think they are running under actual KDE Plasma. Its been a while since i took this screenshot, so ive already forgotten which env vars i set to make this

Realitically they would either make a qtwidgets renderer to make it compatible with existing themes, or extend upon the existing rn skia renderer (the only existing renderer w/ linux support i think)

KDE Plasma 6.7 To Provide A Much Better Experience For CPU-Based Rendering
KDE developer Xaver Hugl has whipped up another nice improvement for the upcoming Plasma 6.7 desktop release. Due to QtWidgets still relying on CPU-based rendering and finding the performance subpar with Wayland shared memory "wl_shm" usage, Xaver has leveraged UDMABUF for avoiding excess buffer copies to provide a much more fluid experience when dealing with CPU-based rendering / shared memory usage on KDE under Wayland...
