This is a large behavioral change for all Chrome users on Linux except those on
NVIDIA's drivers. I think it's too great a risk to take. Instead,
disable_transparent_visuals should be the default, and it should be selectively
enabled on drivers known to work.

Done. Exception is for mesa drivers only. I tested on intel and "nouveau"
drivers but I have not tested the opensource driver for amd hardware, but since
it is mesa, it should be the same code/mechanism underneath for the visual
selection. Also initially this issue was only reported for NVIDIA proprietary
driver.
