Global bins are wonderful—thanks!
The Mask Tool works well. I don't know what I did last time. During testing, the old CinGG tool window suddenly popped up, but I closed it without any issues. Also during testing, I tried using a PNG as a background track. When I tried to extend it to the length of the video track, the timeline and the compositor window froze. All I could see was the PNG. I restarted without any issues.
In “cut and paste” mode, the playhead selects only one region and does not scrub. Is this intentional?
Color3way displayed a corrupted image in the inspector. Everything returned to normal when I enlarged the inspector to fit the entire image. The color wheels work, but the “value” and “saturation” sliders are inactive and do not work.
The Histogram Bezier window was also larger than the Inspector window and was only partially visible. It was also frozen and not working. When I enlarged the Inspector window, the image remained frozen, but a new one appeared below it that was active, even though it wasn't working properly. I didn't find any error messages in the console.
NB: I'm using Wayland; is that a problem? I can certainly use X11 for testing.
