Dear package maintainer(s), In case it is useful information, this issue affects me as well, and has for several weeks. Chromium is usable for only a few minutes before it crashes with a backtrace almost identical to those already shared. It does not seem to matter how many or what kind of pages are open, or whether the browser is actively being used / receiving window manager focus or not.
Please let me know if there is anything I can do to help identify the problem or test a fix. -- Jonathan
