Corruption happens to me on Gnome on Fedora 30 after the update from:

xorg-x11-server-Xorg-1.20.4-3.fc30
xorg-x11-server-common-1.20.4-3.fc30.x86_64

to:

xorg-x11-server-Xorg-1.20.5-3.fc30.x86_64
xorg-x11-server-common-1.20.5-3.fc30.x86_64

I get corrupted icons in Gnome's top panel (specifically the Quake and Dropbox icons (I use the topicons-plus Gnome extension)).
I also get corrupted tooltips in Firefox, e.g., hovering my mouse over my account circle in GMail produces corruption similar to the screenshot shown on this bug.
As suggested by OP, downgrading xorg made the problem go away:

$ glxinfo -B

A comment on a different bug describes a similar problem, and he has an AMD card as well:
