I had reinstalled ubuntu 20.04 and all was working well with the touchscreen.
I installed all updates one by one and it was working too.
Changed on prime between intel mode, nvidia on demand and nvidia performance mode too.

I was able to reproduce the bug when I activated "fractional scaling" and set it to 150% on gnome settings.
Since this the touchscreen doesn't work anymore on my ubuntu session. I had disabled "fractional scaling" and set to 200% like just after the installation but it doesn't work anymore.

Tried again with nvidia and intel mode with the same result.

Can it be a bug related to gnome ?
