Animate CC has a serious bug pertaining to all Tablet PC devices using Windows 10, whenever you start to draw you will receive a lag that draws a straight line from where you started to put your pen down to wherever your stylus is at the time the lag is complete.
I would like to start by showing how real and sever this bug has been to the Animate CC community by referring to past forums I have found regarding this very same issue that goes back as far as 2013. All these posts are by the various professional users who are not able to use Animate CC properly on their tablet PC device. Many of these users (including me) need to use Animate CC as a source of income. Please take a look.
From what I can tell this issue is part Microsoft windows Ink's doing and part Adobe's doing. Microsoft released their Windows Ink update a few years back which did not sit well with many Adobe users. Over time Adobe has been able to accommodate this change by Microsoft, but has not yet solved all the issues for Adobe Animate CC leaving it's users wondering why there is no fix and resorting to reverting back to Windows 7 or abandoning Animate CC altogether for other animation packages. It's been very frustrating using Animate CC to draw because of the initial drawing line bug for many tablet users. For Adobe developers working on AnimateCC, I'll tell you everything I know in hopes of making this your top priority. The below image contains blue circles that I drew to demonstrate the issue. I'm using the absolute latest version of AnimateCC and Windows 10. This issue persists on AES, N-Trig and EMR devices. So yes, Surface Book users will experience all these pains when trying to use Animate CC. I circled the problem areas in red which are essentially the initial start to the drawing of the circles. Ironically the red circles are also warped due to this bug. Keep in mind that I'm a professional artist and drawing circles is common practice for me. Pay notice unintentional lines that are created from my brushstrokes.
Let's look deeper into this issue. A big clue is that Windows uses screen holds to simulate right clicks. Below you can see this in action and how it relates to the issue. The radial matches up with the initial drawing line. Keep in mind that with Hold Right clicks turned on I am NOT able to draw until I cross that radial threshold. You are not able to see it in the below animation but I am scribbling inside that radial circle during the time it looks like my cursor is frozen in the center. Only When I leave the radial area does my line begin to pick up.
Now lets turn off Hold To Right Click
Just like previously, when the below cursor animation freezes I'm actually scribbling around a bit before I leave that now invisible radial area (at which point I'm not able to draw) and the drawing picks up with that straight line. If you are thinking in your head "this guy is claiming he can't draw dots or tiny circles" then you are correct.
but let's go ahead an turn on that Microsoft legacy patch that everyone's been talking about for photoshop (which is not needed currently with Photoshop CC). Then restart flash
what seems to be happening in the animation below is that the radial area seems to have gotten a lot smaller (maybe 1/5 the size) but still receiving the line drawing lag.
The faster you draw the more obvious and large that lag line becomes so the patch doesn't really fix much.
Below is just demonstrate how consistently bad this bug is. This is me trying to draw semi-circles. Red AnimateCC / Black Photoshop
Please, please, please fix this bug as I need to make a living animating using AnimateCC. I have been a loyal Animate CC user for many years and have integrated Animate CC into many great projects. I do not wish to leave Animate CC and begin working with a new package, but unfortunately, I don't have much of an option at this point.
