Weird scaling issues on MATE

Hello. I'm trying MATE, but there is something really off about it.
this is how google drive looks on Manjaro MATE running on the native hardware:

And this is how it looked on a virtualbox (fullscreen, same resolution)

this is how it supposed to look and how it looks on every other distro^
it's not exlcusive to the google drive website, just an example. and the weird thing is, it also happened when trying to run Ubuntu MATE, so it's seems to be MATE-related problem with the hardware, rather than manjaro mate's problem.

i'm using nvidia gpu if it matters.

Hello,

Have you posted this in the Mate forum? That seems like a good place to start?
