disabled hardware accelerated graphics on hp laptop

Hey guys, this is basically a part 2 to this forum thread.

Basically, x kept crashing (and wayland as well) on my HP ProBook x360 440 G1. The only solution so far has been to create /etc/X11/xorg.conf.d/20-noaccel.conf:

Section "Device"
        Identifier "intel"
        Driver "modesetting"
        BusID "pci:0@0:2:0"
        Option "AccelMethod" "none"

The problem with this solution is that software rendering is really, really slow. I have issues with zoom, and running simulations like this.
I had to close that window because my cpu was at 80% on all 4 cores.

I've tried a few other configurations using xf86-video-intel for completeness sake. I tried maximum DRI level 2 with uxa accel method and with the defaults. DRI 3 and sna causes the x server to instantly freeze the entire system. uxa 'works' but it is even slower than software rendering and I don't know why. None of the configurations other than the one above with the modesetting driver are usable.

This is clearly some kind of hardware issue. Does anybody have any suggestions for how I can troubleshoot this?

It sucks, but be would need *some* data on the crash and if you can't eg. ssh into the crashed system, the crash kernel is the only way to get there.
