SUMMARY
When toggling WCG in a terminal with kscreen-doctor, after pressing Enter to execute the command, the screen flashes (as expected), but the terminal does not seem to receive a release event for the Enter key.

STEPS TO REPRODUCE
1. Open a terminal (Konsole Wayland or WezTerm XWayland) and type "kscreen-doctor output.<output-name>.wcg.enable" (or "disable" depending on its current state)
2. Press enter

OBSERVED RESULT
The screen flashes, and after returning to normal the terminal prints the command prompt continuously as if the Enter key is held down.

I cannot reproduce this anymore with KWin fd2e77317f99b159bb023420051be17383520bae.

Toggling WCG does not make the screen flash anymore, but toggling HDR does. Either way, the Enter key no longer appears to be held down in both cases.
