[19.10] Tri-screen hell

@layingback Thanks a bunch. As usual, you've made me a more intelligent person and I thank you for that <3.

So even though I wasn't actively "supporting this thread" lately I felt like I needed to report something else that I felt could be related to using several monitors but that I am yet too dumb to conclude on this.

(And/or maybe this also relates to one of my previous posts @ [19.10] Why doesn't my text cursor stays in CAJA? but am counting on you fine folks to tell me)

So you be the judge:

Earlier today (and every now and then) it happens to me that my resolutions gets TOTALLY fsck'ed up on TTY7. And what I mean by that is that some of my windows are cut or simply missing parts (like 1/2 or 3/4 of them) when 1. everything has been working fine for a couple of days and that 2. I powered off 1 monitor and repowered it on a very short time after.

But this problem doesn't happen all of the time. More like once every 20 tries.

So, I had Firefox opened on my left screen (and a bunch more of opened windows mind you) and powered off my left monitor thinking I would be stepping away for sometime. But immediately after I had to rejump in the Matrix so I powered my left screen back on and the half bottom of FF was displayed but the first half part of my screen was only showing my background (And my icons were now displayed on my right monitor which is NOT set as my primary monitor).

I also need to mention that the MATE menu had just dissapeared from the top of my screen alongside the status bar at the bottom (with my currently opened windows). Per my previous community experience, I switched to TTY1 and killed marco thinking that was it.

But I was wrong.

Back in TTY7: I couldn't select anything, nor make sense of anything that was going(ALT+TAB=failed, ALT+F4=failed) on as it seemed that half of my "forefront" pixels were flushed into The Twightlight Zone.

Since this wasn't the first time that I experienced this(possibly been having this for 2-3 years but w/out consistency), I just logged off and relogged back in and, of course, that "fixed" it.

So, here I am yet again asking you, oh dear Community, if anyone ever had this issue (or something similar) going and if so you can help narrow it down so we can squash this once and for all?

Best,
