Gradient doesn't work! about fyne HOT 13 OPEN

I think this may be because color.White and color.Black are not in the RGBA colourspace. We can probably do something to help with this.

However you could help us test by using &color.NRGBA{0xff, 0xff, 0xff, 0xff} and &color.NRGBA{0x00, 0x00, 0x00, 0x00} to see if it works.

Can anyone on Linux Mint please run the code and verify?
I cannot replicate this on any computer.

I think really we will have to dig into what GPU you have, and what graphics driver @nchistov

@andydotxyz my GPU is "AMD Radeon RX 550 Series". And how to see what graphical driver I have?

from fyne.

But I install these deps: ... libgl1-mesa-dev xorg-dev as in documentation for Debian/Ubuntu linuxes.
