Animation timeline thumbnails messed up

I still see my timeline thumbnails messed up. I am running Mac build xv.14.3-arm64. I heard this was addressed and it worked a little better after the update, but it still see it wrong.

Am I running the latest build? I get it from Steam.

Thanks, Ron.

Are you referring to the white boxes around the bow and the sword?

What is the sprite’s color mode?

Do you sometimes use transparent white (R 255, G 255, B 255, A 0) as a mask color instead of transparent black (R 0, G 0, B 0, A 0)?

The image above shows what happens when an image purposefully contains transparent cyan and magenta. As a consequence of the timeline thumbnails being messed up, they are – ironically – a good tool to detect problems with transparent colors.

You can see what version you’re using by going to Help > About in the menu bar. I’m using version 1.3.14.3-x64 through Steam on Windows 11, which is the latest build afaik.

Color mode is RGB. Most of the tumbnails look fine, just a few have the white background and one of totally messed up. Looks like pixels are shifted around.

The all worked fine for years, then it was messaged up a few builds ago. I was told that it was a known issue and would be fixed in the next build. It got better in the next build but didn’t fully fix it.

a software that is continuosly updated is always subject to entropy, the code changes and will bugs happen, we just gotta wait.

The scaling issue was fixed, but it looks like another problem here, probably the timeline is not being refreshed properly in some cases (e.g. after drawing something in an existing cel, the timeline might show a thumbnails of the previous state of the cel until we move the mouse above the cel or press F5 to repaint everything).

Anyway the issue with the white background looks like another kind of problem.
