After removing the xf86-video-intel package and changing the driver in /etc/X11/xorg.conf from "intel" to "modesetting" I got rid of most issues.
lots of distros don't recommend using xf86-video-intel (read more about that in https://wiki.archlinux.org/index.php/Intel_graphics#Installation)
Google Chrome is known to have some issues with the modesetting driver, but not the problems you described (https://bugs.chromium.org/p/chromium/issues/detail?id=370022)
