Sharex: Lag when painting with pen tablet

[vicro]

When using a wacom pen tablet to annotate an image. There is a lag after pressing the pen into the tablet for painting and actual painting happens. A UI circle appears and after dragging the pen for about 100 pixels it finally starts painting.
This makes it very difficult to paint annotations. This happens with the pencil, lines, arrow and other tools.

Using Windows 10, Wacom Intuos Pro.
This does not happen when using a normal mouse to paint.

How do you think that I can test such thing?

This does not happen with Photoshop, or other painting tools by the way.
If you could point to places in the code that could be related or something that comes to mind.
I assume that you have no pen tablet to test.

I found a workaround, would also appreciate some fix in ShareX if possible.
If I uncheck the "Use Windows Ink" in the Wacom properties window it works I can set that per program so I only uncheck it for ShareX.
Is the ShareX editor window enabling/disabling something related to Windows Ink?

No.

can confirm an issue with Windows ink on windows 10.
the only way to test it is to use any tablet with windows ink enabled.
here's a little demo of "lag" http://tinyurl.com/y4vyxqap

For what it's worth, when I start dragging the pen tip on my drawing tablet, the first 25 pixels (your mileage may vary) is ignored. I'm not using a Wacom but a cheap Hanvon whose settings utility is really basic, and there's nothing like 'Use Windows Ink' checkbox. Apparently, this issue is not at the top of the list, so I found a workaround: launch MS Paint 3D after capturing.
The steps are:
1) open ShareX main window
2) activate both 'Save image to file' and 'Perform actions' under 'After capture tasks' menu
3) Click 'Add' and fill in the first three boxes (Name/FilePath/Arguments) with:

%Windows%\System32\mspaint.exe
%input /ForceBootstrapPaint3D

5) Make sure the new profile (Pain3D) is checked

Although it works well with my drawing tablet, I find Paint 3D a little bit slow to use. I'm trying other free image editing tools such as Paint.NET, mypaint, and FireAlpaca. They have brush tools suited for drawing tablets without a lagging issue.
Having said that, I hope the lagging issue is solved in the Sharex's image editor. It's got all features I expect from a screen annotation tool: freehand drawing, basic shapes, highlight, and text.

Same here. The lag seems to be time based and not distance based.
