What is your operating system?
It is Artix Linux
What is your Shotcut version (see Help > About Shotcut)?
23.09.29
Can you repeat the problem? If so, what are the steps?
Very simple, Shotcut works perfectly with Qt6 version 6.5.3
If I updgrade to Qt6 version 6.6.0, the timeline becomes a white square. I had to downgrade Qt6 to be able to use the application. Please consider this bug for the next Linux release.
It is only supported with the version of Qt we use in the builds on our download page. If you or your distro builds it with a different version, then someone other than us should fix it. We are not in a rush to use Qt 6.6 because it drops older versions of macOS and Linux.
Also on GitHub
A fix was submitted on GitHub and merged, but I have not tested it. Since these are installed QML files loaded and interpreted at run time, you can try to make the changes for your install:
Or, just copy the changed files CornerSelectionShadow.qml and timeline.qml from the git repo in their entirety:
Archlinux has published shotcut v.23.09.23-2 last sunday which fixes the problem.
Thank you very much and I beg your pardon if I waste your time.
