So, I was downloading some Patreon stuff and Patreon isnt well optimized for browsing older posts. When you have to load multiple more pages dating backwards it slows down the Firefox quite a lot, pretty much to the point when the Firefox reach non-responding state in worst cases. But luckily for me Patreon worked fine for me tonight, just when I was closing the Firefox, it took like 5 seconds for it to close. I spent some short time by responding messages on Steam and Discord and then I started new Firefox window, this time I went on Netflix and when the page loaded my monitor went black and then after like few seconds it returned back with "Displayport" message on the top left corner. When I checked Event viewer, there is nothing at all. When I checked about:crashes, there is also nothing. Any idea what was that and how to prevent that?
