Same issue, but I noticed ALL Chrome based browsers show this issue, for me … Chromium, Chrome (stable), Brave … oddly, Opera renders fine.
(With a couple of odd exceptions) I always update a laptop first, reboot, and briefly check for any issues. All was fine after update (even Chrome based browsers), so updated other laptop … all fine.
Then I updated the 1st desktop. Chrome browsers fail a proper render. I booted the second desktop … same issue.
HOWEVER … Chrome Beta works on the primary desktop.
Using the Slate theme as default … switching themes, or not using one, doesn’t change. “Use GTK” or not, doesn’t change. I use “Auto Dark Mode for Web Contents” found in “chrome://flags” - altering that doesn’t change the issue.
If I’m bored, I might further investigate …
But yea, if you rename the “chrome stable” subdirectory found in the “/home/username/.config” subdirectory, that’ll fix it, but doing that is like “starting Chrome for the first time after installing”.
