I use a Dell Precision M4800 with Ubuntu 20.04.3 LTS
And I am having an issue where any browser I use (Chromium, Firefox) constantly crashes. Typically it just goes to the screen on Chromium,
" Aw Snap! Something went wrong while displaying this webpage."
and similar messages. Occasionally I'll have all of my windows crash (close completely). I have ran a memory test and it appeared to be fine (not an expert). This has been happening ever since I installed Ubuntu on this system, so the issue was present on previous releases as well.
