I'm not seeing anything recent on this, so I'm guessing its not a widespread issue anymore. But, its been an issue for me the last couple months.
Chrome (Currently on 96.0.4664.45) crashes frequently. Mouse is responsive in the Chrome windows but buttons and keyboard aren't. The rest of the system remains functional. I can kill Chrome using pkill & restarting allows me to restore at the point it froze. Usually there's no crash message, but there is a crash file in /var/crash. That's about 100MB and I can't seem to find anything in it to tell me WHY (although I'm pretty clueless on what I'm looking at).
My workflow results in a lot of open tabs, but HTOP shows there's usually about 54GB of RAM free (out of 64) at the time of crash. Memory tests OK with memtest and the motherboard's diagnostics.
Not sure what to check next? TIA for any recommendations.
