Pinching the screen (especially with single hand) doesn't reliably zoom images and I have to try multiple times to get it to work

Sometimes when scrolling it just abruptly starts scrolling up with massive speed. I don't know how to reproduce this issue.

In the bad ending of the game, you bomb some volcano looking region of the city with what looks like nukes to kill the dark ones. Got lots of questions about that. Why was that area glowing red? Why were the dark ones thought to be there while during the game they were quite close to human settlements? Or if human settlements are under that red area, doesn't bombing it also harm the humans? And why exactly was the objective bombing the dark ones while nosalises were shown to be the main threat to humanity? If polis station had accepted helping, would they also bomb the red area? I was under the impression they'd come to Artyom's Station and protect it manually. Also if those missiles were nukes, won't that just create more mutants? Are these ever explained in the game or the books?

I don't know what exactly the file names are, ls shows one of them as ''$'\320''"m'$'\254\032''V' and fish shows it as \Xd0\"m\Xac\czV. Inside the file is

[KCrash]
exe=P π¬V
platform=xcb
display=:0
appname= Π¬V
apppath=ίλ&ΝV
signal=11
pid=23560

I think this is something about xorg, but can't figure out what it is. Does anyone know what it might be and how to fix the issue? Also I don't know how to decode the file name or the strings in the file, so please tell me if they might reveal personal information.
