Anything else we should know?

three years ago, obs fixed a QT bug:

UI: Disable QT's implicit colourspace conversion on macOS

Fixes issues as described in https://bugreports.qt.io/browse/QTBUG-47660
and halves CPU usage of OBS' UI by about 40-50%.

but now using qt6, the bug already fixed by qt, so obs should restore the window color space.
