CEP Extension, Flickering Cursor when using touch events

Hello,

I'm using the lastest Photoshop CC, currently ver 19.1.0 on Windows 10.

I'm trying to build a small Photoshop extension (a panel).

I've built a little HTML/JS interface.

When I use my mouse to interact with it, everything works fine.

However, when I try using my graphic tablet (which triggers touch events) I get a strange behaviour :

Whenever I drag my pen (touchstart, touchmove, touchend) in my panel, it triggers the thing.

Then, when I hover my pen over the main drawing canvas, the cursor flickers and I have to click once to stop it.

I should describe better what I call flickering. When the cursor is over the canvas without moving it has the right appearance (the one of the tool i am using), but when I move it, it changes to the regular windows cursor.

It's like the cursor is in-between two states, or maybe it's a focus issue.

I tried releasing the focus using the event "com.adobe.PhotoshopLoseFocus" on thouchend js event.

But it didn't help much.

Maybe one of you has already had this issue.

Regards
