SUMMARY

I'm developing a script and when I change something in the code - I build and install it. When the installation is finished, the new version of the files becomes available in the installation location. However, when I turn the script off and on - KWin still uses the old version of the script. If I restart KWin the new version is used, but that's inconvenient and is not possible on Wayland session.

STEPS TO REPRODUCE
1. Install some script and run it.
2. Change the script source, so that it outputs some new line to the console
3. Turn the script off and on.

OBSERVED RESULT
No new line is printed

EXPECTED RESULT
New line is printed in the console

This makes QML-based script development on wayland impossible (AFAIK), at least as long as "main" KWin is used for testing.

I guess https://doc.qt.io/qt-6/qqmlengine.html#trimComponentCache in right place would fix the problem.
