Rasterization broken in chromium browsers

[Catloaf2019]

Expected behavior: rastered content is smooth like so:  

Observed behavior: rasterization is very pixelated: 

 

Workaround: go to about:flags and change #enable-gpu-rasterization to disabled, however this makes sites such as geogebra.org/calculator run very slow.

I should also add that the issue is better (but not gone) when using chromium with the proprietary mali blobs and --ozone-platform=wayland

 

It is also improved (but still not as good as software render) by using the flag --use-gl=angle, but that breaks video decoding
