[SOLVED]Display freezes when move mouse past the left side of screen.

Description:
I upgraded to a 4k monitor LG 27BL85U. The monitor is driven by an NVidia Quadro 400 (nouveau drivers) connected via a DisplayPort cable.
Previously, I was using a widescreen LG 25UM57-P connected via HDMI.
Whenever I "touch" the left edge of the screen with the mouse, the display will crash. The screen changes color to the normal desktop background color but the mouse pointer disappears, all open windows disappear and any window decorations disappear. I can not get the screen to come alive by switching to any of other ttys. I can ssh in. If I have audio playing etc, it will persist and continue to play after I break the screen.
This will happen both in icewm and fluxbox.
If I drag a window and cross that left edge boundary to move it to an adjoining desktop, the display doesn't crash.
It only occurs when I touch the left edge of the screen. The top, bottom, and right edges aren't allergic to the mouse.
I've been living with this for probably the better part of a year. I typically run pacman to update the system 1x / week.

I searched for

etc on the web and the issues that popped up seemed to be related to old kernels.

Let me know if I missed any relevant information or details.

I appreciate the help.

Re: [SOLVED]Display freezes when move mouse past the left side of screen.

Try
a) the modesetting driver (drop xf86-video-nouveau)
b) software cursor, https://man.archlinux.org/man/extra/xf8 … .en#Option
c) nvidia-340xx

Re: [SOLVED]Display freezes when move mouse past the left side of screen.

Seth, Thanks for the reply.

1) Issue still occurred
2) This worked although there is some weird screen updating / painting going on. Since this solved the crashing I'm more than willing to deal with the screen painting weirdness. The screen weirdness involves some of the fluxbox chrome not properly repainting and having the background go all black when I launched my first program. I had to "paint" the background by dragging the application window around to get the background color to be painted correctly.
3) didn't try due to #2
