@Dalai Felinto (dfelinto). I think this is fine. I now have a workaround, as you wrote. Thanks for looking into it.

So I dig a bit further with blender-2.81 0547a7753643:

Thanks but we can't use private files in your debugging process. Another round of questions:

I tested it again with blender-2.81 0547a7753643 but still the same issues with older Blender file.
I have attached a video where you can see the behaviour. And in the same video there is a test with the same video file, but with a new Blender 2.81 file from scratch. Here are no problems and the prefetch works as intended.

@Michael P. (forest-house) Can you test with the official 2.80 release (blender.org/download) and also a night build (builder.blender.org) to see if the problem persists?

D5400: Make name of Active Clip consistent in UI is now accepted and ready to land.

Fine with me. If it's the same thing we should name it the same, otherwise it causes unnecessary confusion.

Brecht Van Lommel (brecht) added a comment to D5400: Make name of Active Clip consistent in UI.

I think it's ok to rename, this kind of API breakage we'll have more of in 2.81. This particular property is not used in any bundled add-on at least.

Sergey Sharybin (sergey) added a comment to T66872: Changing the Colorspace settings of a Movieclip is not properly updating Camera Background Images.
NOTE: The issue is not limited to the color management, and actual solution is to make movie clip cache shared across compositor, render engines, editors and so on (currently those are decoupled).

Rainer Trummer (aliasguru) added a comment to T65589: Datablocks can't be duplicated everywhere, because trick with fake user no longer works.

I'm also not a huge fan of hiding the existance of fake users in the UI. While I understand that it confuses new people (trying to avoid the term "new users" here for clarity's sake), it also "forces" them to learn about how Blender handles data in general, and what the concept of user counting is. A fake user IS a second user of a datablock, as long as there is something else referencing the datablock. Not showing that will all the more confuse all the other people who have learned about the user count system.
