Just bumping this in case anyone has any fresh insight into this as I've never resolved it.
I've searched high and low on the interwebs, trying all sorts of combinations with the gpu & javascript settings in chrome:settings but to no avail.
Interestingly this issue isn't just confined to Solus but if I install any Ubuntu based distro with any DE then I get the same problem.
When I run a live USB then Chrome browsers run OK, as well as on clean installs, so I'm guessing that it's something else I've installed on my system that is causing this but I can't for the life of me figure out what it is.
My machine is an AMD Ryzen 4800H with Renoir graphics.
