Thanks for reporting this problem, @Azy. We tested on a couple different computers and didn't see the problem, so it looks like it's specific to the GPU. What GPU do you have?

Yeah, your idea that maybe your barcode is being identified as the wrong kind of barcode sounds plausible. And adding the option to select the type of barcode (or to have it auto-detect, as it does now) sounds like a good fix, as well as a possible performance speedup.

@jstrecker commented on @lechbialek's Feature Request, “Play MIDI files (vuo.midi.play.file)

Thanks for the suggestion, @lechbialek. Opened for voting.

We've decided to make it a Pro feature based on our guidelines, How do you determine which features are only in Vuo Pro?, as we see it being most useful in conjunction with a MIDI sequencer.

Aha, looks like the issue is not graphics slowness, but a side effect of the way that Make Text Layer renders sharp text.

Make Text Layer snaps the text to pixels so that it's totally sharp rather than blurred across pixels. However, as your composition points out, this can interact weirdly with scrolling text across the window. To keep the text sharp, Make Text Layer causes the text to jump from one pixel to the next. Depending on how the scrolling events line up in time with pixels in space, the text could actually move 1px or 2px or 0px on a given display refresh. Hence the jerky motion.

If you remove Make Text Layer and just use Make Text Image — which, when combined with Make Image Layer non-realsize, does not snap to pixels — that should be smoother. With the attached composition, if you slow down the scrollers and zoom in, you can see the pixels gradually fade in and out as it moves along.
