Replying to https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=926032#100
Thanks for clarifying. I was actually confused by your previous comment, since I wasn't using that version, 75.0.3770.90-1. Now that I know, there are some bugs in that version which makes hardware acceleration ON always, and the option to revert to software rendering is gone. Regards, Aik Hong Tan (previously, Wallace)
