While attempting to boot the elementaryos-5.1-stable.20200814.iso installer with an AMD Radeon 550RX with 4GB RAM I'm seeing corrupted graphics and not sure how to proceed:
For what it's worth, I ran through the installation with another older significantly slower GPU and then updated the system following the install. I then put the 550RX back in and was met with very similar graphical corruption.
Update 1 - still no joy:
Attempted to follow these instructions wherein I then installed the drivers from AMD for 18.04.5 HWE.
lsmod shows:
$ lsmod | grep amd
amdgpu 4530176 0
