Missing cursor when hovering with a Trust Flex tablet in Ubuntu 16.04

Continuing the discussion from MyPaint 1.2.0 Released!:

I'm using MyPaint on Ubuntu with a Trust Flex tablet. I just updated both system and MyPaint (16.04 and 1.2.0). The changes look great and the pen pressure works just fine, but when using the pen I can't see the pointer until I press it to the tablet. This is a big problem, obviously... It isn't a feature, I hope?

No, it's not a feature.

Do you get the same behaviour in gtk3-demo → Drawing Area (double click to launch) → Scribble Area? Install the gtk-3-examples package before trying this.

Do you get the same problem in GIMP? Which version of GIMP?

I took another look and it seems this is a problem between Ubuntu and the Flex tablet, since the cursor doesn't appear with any other app, either, though touching it to the tablet still functions like a click. Sorry for bringing it up with you, seems like it's nothing to do with MyPaint!

And, who is that fixed?
I have the same problem and not found a solution yet

Hi there - similar issue here.
Everything works alright with the mouse.
I’ve got the same problem - but it is related to the pen.
The cursor disappears when I hover over the tablet with the pen.
I can’t draw properly as I don’t see where the pen is actually going - but it does draw if it touches the tablet.
Does not happen with GIMP. I can see the pen hovering.
Device is a Waltop Slim 12.1" tablet. (ID 172f:0034).
Ubuntu is 16.04 LTS, stock drivers out of the box.

This started when doing a new clean install for Ubuntu.
It was working properly with Ubuntu 14.04 LTS and MyPaint of that version.

Any ideas of how to circumvent this?
