You aren't going to see any reasonable performance on this chip in Linux. It's from an older line using the radeon driver. Going forward all development is in the amdgpu driver from AMD. This only applies to recent and future cards. There are a huge number of outstanding issues that have not (and will not) be fixed. It's an obsolete product.
As for why you get artifacting in the desktop but NOT the installer. Compositing. Gnome3 is GPU-accelerated. If your gpu is not fully supported bad things will happen. This is common on older AMD and some intel chips. Good workarounds are: - adding nomodeset to your kernel commandline ( this works wonders for an X11 based desktop ) - switching to a desktop environment that does not force hardware acceleration. Xfce is a popular go-to for this problem. This is also a very OLD problem so maybe users here should make a note of the fact that AMD's gpu support does not go back to the radion 4000's.. There is literally nothing to troubleshoot, it is broken, known to be broken, and will stay broken. For more details, ask the guys at FreeGeek why they keep Linux Mint MATE in their back pocket for installs on older hardware. Cinnamon is based on gnome3, and has serious problems with old radeon cards.
