Eraser bug

I found a problem with the eraser. When working on a canvas larger than 1800~x1050~ the eraser will stop functioning properly outside of that portion of the canvas. It will still erase whatever you draw over, but it will not show it until you let go of the button/stylus. I noticed this on my large sprite animation document I showed in my other thread.
I do not believe it's linked to that specific pyxel file though, since I tried it with a completely fresh file and the same issue showed. I also recorded it:

Since it doesn't seem to be an issue of size I'd regard this as a big issue from now on.
Using the latest version 0.3.108.
Addendum: Seems to be a separate issue where resizing the canvas causes a similar issue to the one I first reported because I did the same as last time and tried with a new document with a canvas sized like the one where I noticed the problem, and there was no problem. Restarting Pyxel and loading the document again fixes the issue.
The eraser problem with a large canvas size is still present. (Don't know if you've tried to fix that yet though).
