I experienced this as well, after upgrading to the latest version (Version 1.10.93 Chromium: 83.0.4103.106 (Official Build) (64-bit)).
Please fix it ASAP, as I work all day with an affected site and I cannot stand it anymore. If there is a temporary fix or a workaround, please let us know.
I downloaded an updated version via brew and it shows the same version number (1.10.93 Chromium: 83.0.4103.106) and it shows the same behaviour. Maybe it’s only an issue with brew.
