P1: Critical It is simply reproducible by loading www.google.com.
Fonts are not visible, I'm not sure what changed but it worked before. I've tried older versions too and it is still reproducible. If I try it in debug I get error message:
[323:1:0419/165548.592677:ERROR:memory_mapped_file_posix.cc(39)] fstat 124: Operation not permitted (1)

It can't load the fonts like /usr/share/fonts/liberation-fonts/LiberationSans-Regular.ttf
It works if sandbox is disabled (--no-sandbox).
It is reproducible with 80, 87, 88 based Chromium. I don't think it is a regression, I guess it is result of a system package update but Chromium works fine (system installed and custom built). I can't reproduce the issue on Windows and macOS.
