Color wheel and paper texture not updating in Painter 2021


I have a problem with the color wheel and the paper window in Painter 2021.

First, when I select a new color, the color of the inner triangle doesn't change. The circle indicating the current color changes if I touch it (for example, when it supposed to be brighter), but I can't preview it. 

The same happens with the paper window, if I change the paper texture and settings (scale, angle, etc.) it shows when drawing but I can't see what I am doing before I actually use the brush.

I have a dell xps 13 9310 2 in 1 with a Intel Iris Xe GPU, i-7 CPU and 16 GB of RAM. Running the report on performance from Painter it gives me 4033 points. I don't understand why these basic things don't work properly.

Does anyone have the same issue?
