Fixed crash on start on Wayland on Ubuntu 22.04 and 23.10 - may require installing qt6-wayland package (broke in v23.11).
This breaks support for Wayland on Ubuntu 23.04, which is a less important version than the other two.
The combination of Wayland and Qt 6 seems impossible to handle universally in the portable/AppImage/Snap binary bundle. If installing a Qt 6 Wayland package does not work in your distro, some options are to login using an X session instead of Wayland or try the Flatpak.

Fixed crash in No Sync video filter with new Ease Back and Ease Elastic keyframes.
