I'll throw in my 2 cents on this issue, I'm using Chrome on an Android + I'm in the Philippines and I'll try and explain what I've been going through:
On Start-up: Whenever I open Chrome and it opens into QQ it's just a blank screen, grey. I can still access the Chrome topbar and reloading the page fixes it, but I have to do that everytime.
Switching Tabs in Chrome: Tabbing out of QQ to go into incognito mode or access another page then Tabbing back to QQ makes the page go blank again, hides the topbar, and attempting to just tap on the screen makes the page go white and brick Chrome making me restart the app. This happens like 60% of the time, kind of depends on how long I spent on another tab, but also just happens even if it was just a really fast redirect? Maybe it's something to do with power and resource saving on Chrome.
Switching Apps: I would say a good 80% of the time whenever I leave Chrome running in the background and then switch out to another app like YouTube or something, tabbing back to Chrome gets the same issue as above. Grey screen, no topbar, clicking makes it go white and bricks Chrome. I can still go into the task view, like the button to the left of the home button, but I can't take focus off of Chrome or it will brick itself.
Back Button: Using the back button too much too fast has a high chance of just giving me a blank page, but I do have the topbar accessible so I can reload the page.
I don't know how much this will do but that's my documented experience for these past few days. Also I didnt realize we got jumped by bots.
