Slow strokes on iPad

as much as I love FlipaClip, there is one event that I find VRY annoying.


The strokes o latest ios on an iPad 12.9 gets slow before they hit the final Apple Pencil tip.

There is a certain amount of lag that prevents the user feel comfortable with the sketching experience into the app.


Please note that this is already fixed in other apps like procreate in which NO lagging is apparent.


Can’t we have eventually a real-time representation of Apple Pencil strokes without any kind of delay/lag ?


Pleeaaassseeeeee


The app is perfect it is this feature -along with undo/redo gestures- that I am missing still

Draw lag on first gen iPad Pro

I use a first generation iPad Pro (12’’ screen) and after I’ve been sketching for a little bit the app begins to lag whenever I draw a new line, making sketching and inking uncomfortable. The app also begins to slow down as well. This has been an issue for me since I got the iPad around a year ago, I’m not sure if it’s a software bug or hardware issue. Procreate works fine, for what it’s worth. 

Apple Pencil Delay when Brushing

When I use my Apple Pencil FlipaClips strokes are delayed and it makes it incredibly uncomfortable to sketch and do lineart. This occurs especially when I increase the speed. Does anyone else have this problem? How do I fix it? T-T

Lagging response when using Apple Pen

Using iPad Pro and Apple Pencil. Recently it has been lagging more when drawing or using any of the other tools. Very frustrating when it takes a couple of seconds to see what I have draw appear on the canvas.

@JONA,

According to the latest ipadOs,Pencil kit api, offers significant Apple Pencil speed improvement.

In fact according to this article:

https://9to5mac.com/2019/06/06/pencilkit-apple-wwdc/

The new APIs require just three lines of code for developers to get the same low latency, UI, and tool palette that Apple uses for Pencil. That includes the drop from 20 milliseconds to 9 milliseconds latency that Apple announced during its unveiling of iPadOS.


You may view from apple’s Site link below how to do that:

Is there ANY. Nance to make flipaclip lighting fast after all?

PLEASE KEEP US POSTED


Hey! Sorry, not responding to your other post. So we are working on a much-improved draw engine. The main focus is to improved response time and to use all Apple Pencil features! ETA... well can't give any but once any news is available I'll make sure to let you know here.

Dear Jona,


I just tried even on latest beta 3.5 (91) on an iPad Pro 12.9 1st gen.

unfortunately the stroke lag issue still exists!

    Confirmed once more that the lag takes place only when Palm is on screen as mentioned above.

    PLEASE let us know if and when should we expect a fix for this

    Thank you for letting me know. I was about to write that a new build is available but you have already updated.

    I thought that maybe the fix "Pan/Zoom/Rotate now disabled once Apple Pencil is detected." would resolve this.

    I'll be further looking into this and I'll update you guys once I get something. Thanks for beta testing!!!

    Jona! 

    I downloaded version 1.3.6 (93). I've been drawing with it for about 20 minutes and it has much less lag. Although not 100% perfect. I would say i experience lag 5-10% of the time as compared to about 50% in previous versions.

    Great progress! It's much more usable to draw long term now.

    @Jona,

    Same here. In latest build there seems to be an improvement BUT NOT exactly perfect yet.

    The lag still occurs randomly here and there and of course when the palm is set on screen -which is the most convenient way to draw.

    PLEASE let us know if and when this is FULLY fixed

    @Jona,

    Still with latest version 1.3.9(99), strokes remain slow and unproductive.

    Can you PLEASE let us know if, what and when should we expect a fix to this fundamental bug ?
