Bug more involved with GTK Breeze theme rather QT When using GTK Styles in KDE > Configurations > Breeze, apps that recolorize window topbar will break while active. In example of gnome-abrt, it makes no render with broken drawing (nodraw?), until you toggle off button. If you use any other theme, like Adwaita or Emacs, it will work normally. But not with Breeze theme. SUMMARY STEPS TO REPRODUCE 1. KDE Settings > App Styles > GTK Styles > Breeze 2. Open an app that has app topbar recoloring, in my case was gnome-abrt 3. Click the ✔️/✅ button in left side, above crash list sidebar. 4. Now the window topbar will be broke because theme until you toggle off. OBSERVED RESULT Broken drawing artifacts, like you move and it keeps repeating in frame. EXPECTED RESULT Maybe recolor app window topbar with preset color and invert any attached buttons in window topbar.

Can you attach a screen recording that shows the issue happening?
Created attachment 177185 [details] KDE Bug Breeze/GTK Video alr, here it is.
Well that's very strange. Unfortunately this can't be an issue with the Breeze GTK theme itself as it's just a bunch of CSS. It's more likely to be an issue in GTK handling themes being swapped out at runtime, which would make it a GTK bug.
