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
