[BUG] wrong color when use hardware acceleration is checked 117+

I disabled GPU rasterization under chrome://flags, and the page can be displayed correctly.
chrome://flags/#enable-gpu-rasterization

Turning off GPU rasterization is probably the right solution. You could try to find a specific "Driver Bug Workaround" (see chrome://gpu/), although I'm not actually sure how to apply those individually.

Could this be related to removed GPU blocklist items?
These commits in particular look suspicious:
