I just noticed the 'Set canvas size' gives me unexpected results when using fullscreen letterbox modes.

Maybe you are using letterbox fullscreen on your project?

Apart from that, set canvas size and unbounded scrolling should do what I think you want.

I wish there was a layer mask property so one could easily specify a layer to mask another one without the need to worry about their order.

Something along this lines, where one could specify the layer to use as a mask, the mask mode (if uses the layer's alpha or the RGB as transparency), and if the mask is inverted or no:

Dealing with layer order for masking is somewhat confusing. With a layer mask property you could link an arbitrary number of layers to be masked by a single one, making management easier by eliminating the need to worry about the order or having to duplicate things.

I adapted my example to use only the snapshot feature without the Canvas plugin, works the same:

Swipe Layouts 2 (no Canvas)

I made an example some time ago but using the Canvas plugin instead of the snapshot feature:

Swipe Layouts Example

I guess it's also possible to do it taking a snapshot and dynamically loading it into a sprite, but I haven't tried yet.

That's what I intend, although I will first need to discover how to force point sampling or how to workaround the lack of it.

I can add a color parameter, but how would controlling the speed work? Right now it just re-randomises every frame, what else could it do?I implemented a refresh parameter in my Pixel Noise effect for CC using the 'framecounter' feed and an adjustable refresh parameter. Basically I incremented the noise seed every X frames by adding something like 'ceil( frameCount/refreshRate )' to the seed.

My Depixelize effect smoothen edges of color clusters similar to Eagle and 2xSaI. You can see a preview here.
