There are many known bugs with visual corruption with RTX 5000 series graphics cards. However I didn't notice any problems with Chromium based web browsers.

I just noticed my screenshot didn't capture the errors. I have attached another screenshot.

So this if probably invalid/wontfix: It is caused when anisotropic filtering is forced globally in the nVidia driver. Shows corruption with RTX 5000 with WebRender, never did with older Geforce generations for me.

I'll leave that assessment to others :-)

I think we've had a similar report previously - the aniso filtering is not compatible with the way we create texture atlases, which causes the artifacts. Unfortunately there's nothing we can do WR-side to prevent this (at least, not without very significant performance implications). Perhaps there is a way we could detect that aniso is being forced by the driver and warn users, or something like that.
