Unfortunately we're still dealing with other new features and addressing different bugs at the moment, but in the meantime, a workaround might be to use the lovely, free drawing program Alchemy and the Screen Capture actor to get that back into Isadora (I've used this method for a performance before and was very pleased with the result).

Best wishes,

as it happens, i love those spiky glitches. something similar popped up in a patch i made years ago - long before Live Drawing actor was a thing. i have no idea where these lines came from, but i tend to embrace glitches like this:

if you manage to fix the Live Drawing code, it would be lovely if there was a way to select glitch or non-glitch variants.

it is OK. Unfortunately I am not able to program so I could help.

Whoa that's gorgeous!

This problem with the Lines vs the Classic Lines actor is something we'll definately investigate.

 Can we expect an improvement soon?

In all honesty, this improvement will likely not be coming soon. There are more important features to core functionalities of the program in the works right now, and side-stepping those in order to improve something solely in the Live Drawing actor would only benefit our users that utilize the Live Drawing actor, (whereas the core changes we're looking at are aimed at making improvements that will benefit as much of the userbase as possible). We wish we had enough capital to hire an army of programmers who could help us improve everything about the software as quickly as possible and to implement feature requests immediately but unfortunately, we don't have those resources so we need to be very deliberate about what areas and features we spend time on developing.

Sorry, probably not the answer you wanted to hear, (and it's not the answer we want to give either), but for now we have to focus on other things.

Best wishes,

This is a known issue. It happens when you make a small, tiny direction reversal (like quickly going a little bit up then immediately going a little bit down). It's a problem that has to be solved with changes to the code.

here a screenshot detail of the lines:

you can see the white line (GPU) is not so clean as the yellow one.

any other setting to tweak?

2. Live Draw actor will frequently create these spiky glitches while drawing.  Seems to be a rendering issue?  Any way to avoid those?

1. LINES actor has a ton more aliasing than Classic LINES which is a lot crisper/cleaner.  Is there a reason for this, and can it be fixed without applying a blur?

 Try going into Isadora > Preferences... > Video > Video Image Processing > Default Resolution and changing it from 640x360 to 1920x1080
