We usually have cicadas which make this very high-pitched chirping that doesn't seem too loud and yet it's oddly deafening. This summer, a new kind joined the gang with a way lower-pitched chirping.
I used to be a moderator on a forum for a while and this is very accurate. Moderation was done according to the rules, and as a result we had assholes constantly testing the limits. That was some proper bullshit. On the other side, though, IIRC before my time someone actually had gotten a lawyer involved due to a dispute with the moderators, so I guess there simply was no winning for us.
The thread says to use the OpenGL renderer. I tried it and it does fix the memory issue, but there's lots of lagging instead. Makes sense that it's very noticeable at 4K.
Got that solved as well. Now the only downside compared to looking-glass is that I can't view the VM through a window anymore which I can just hide when I need to do something on the host.
Ah, I remember why I didn't play Minecraft with this setup. It's unplayable because the camera speed is like 1000x for some reason But at least I don't have to worry about my art projects anymore
@xoagray Hence why I said I might stop playing it on the VM. The thing is, though, that I need to solve this problem because it happens all the same when I want to use software like Affinity Designer.
I'm beginning to think the culprit is looking-glass. That would suck big time because it makes working on both host and guest system simultaneously super convenient.
Well, I won't keep playing Minecraft on my Windows VM if the RAM problem persists. Having to reboot the computer to free up the RAM every 30 minutes is kind of a pain.

Definitely going to report it, though
