Some programs randomly freezing

Hello! Since yesterday I’ve been encountering a very specific issue using Manjaro. At this point I’m nearly ready to give up and reinstall, but I thought I’d give the forum a shot first. I’ll try to describe the thing in as much detail as I can, but I’m no expert, so go easy on me.
Some programs when used cause very odd freezes, which seem to effect other random programs, while having no effect on others.
So far only I have only seen Vivaldi, Firefox and Discord cause the freeze. Browsers are far more likely to do this with Google Sheets open. Once that happens, browsers say that Sheets is trying to connect to Google servers, even though I still have Internet. Once they freeze, they take no input, and can only be closed by terminating them. They also do a thing where if I minimise them, and then open again from the tray, they just copy whatever was on the screen last. Restarting doesn’t fix it, browsers only load the top section and freeze again, Discord only starts an empty window. Once one of these three brakes, the others do as well. On top of that, I also cannot start the package manager, and after a while it seems to break a game running with wine as well. Programs I know aren’t affected are Teamspeak, Telegram Desktop and Spotify. These run without any issues, even if all the rest breaks.
Things I have tried: reinstalling the above software, switching to other versions of the kernel (5.4, 5.9 and 5.11 all did this).

Do I have any chance of saving this without reinstall?

Edited, thanks.

This is what stands out to me:

  1. Your on-board graphics does consume your RAM. So, your useage might not be what is being reported.

  2. With 8GB total ram, I would opine that you definitely need a swap partition/file.

Okay, I see, thanks. Just two more quick questions then. How much swap do you think I need? And how is it only a problem since yesterday?

It is always a problem when there is no swap defined - you will encounter issues sooner or later - in your case it was later.

The default installation has a vm.swappiness of 60 but when there is no swap defined the system goes bonkers - because it is default configured to use swap early but has none. This clogs up the system and you will run into freezes as the system tries to handle early swap with no swap space. To actually run a system without swap you need a system with at least 16GB better yet 32GB - yes I know - could probably be done with less - and a vm.swappiness=10 but still a little swap - like 2GB is always better than none.

Allocated about 10 gigs of swap space, problem persists. It also produce a new thing, where I could use everything with the keyboard I could use before, just the mouse wasn’t working. The mouse is good, I tested it.
