Phone Lock-up Problem

So, I have a very curious problem with my phone. Sometimes, randomly, usually when playing video, my navbar and statusbar disappear completely, and then everything just goes to black, my wallpaper comes up, and then my lockscreen. The phone just locks itself. I use fingerprint, but I need to enter the code to "enable fingerprint". I'm guessing System UI is crashing, but why?

I used to be on stock ROM (Marshmallow), stock kernel, rooted, and had Xposed installed. I had a ton of Xposed modules installed and frankly, I thought one of the modules was the problem. My phone would, as I described lock itself while doing somthing. It seemed to be random, but happened the most while watching videos on YouTube. Sometimes this would happen 4-5 times, and I'd find my wallpaper replaced with the factory default one.

I recently flashed Lineage OS 14.1 and ElementalX kernel, re-installed Xposed (though an incomplete version, the one made by the PurifyOS team) and enabled only 1 very minor module (Android Phone Vibrator). I was very unpleasantly surprised to see the same thing happening, yet again. Not necessarily after enabling the Xposed module . It only happened twice so far, (while using WhatsApp) but the symptoms are the same. My navbar and statusbar disappear, although this time the screen freezes, instead of turning off completely. I can still turn off the screen and open the power menu using the power button.

I can provide logs, or any other info necesarry really, but it's really hard for me to catch logs, because I can't reproduce the error. It's really driving me insane. Please, help me..

@MMMedic Did you resolve your problem?

My Moto G4 Plus has started doing the same thing as you described, even down to changing the wallpaper.

My phone isn't rooted and I'm just using the stock Android.

I'm not sure what to do to fix it.
