I suspect we'll need to hook into .invalidate and .validate and update monitor dimensions in those cases.

Image, which GH doesn't seem to want to embed

@SquidDev Is this bug still relevant? It's a year old now and the image link is dead. I'm not a Java developer so I doubt I can fix the issue, though I have no clue what the issue is exactly.

I suspect it is - I'll try to reproduce it and get a new screenshot.

I haven't really looked at this recently - Quark in a core mod, and so doesn't run in a deobfuscated environment, making it a pain to test changes.

It's also possible to create similar funky issues with Carry On, by picking up and placing down monitors.

I think a good fix here is to verify that a monitor is well-formed (i.e. there is a matching monitor at the origin) when placed/validated, and reset to a single monitor if not.
