Upon upgrading to mesa 17.0.1-2 (from -1) lost ALL 16:9 resolutions leaving only 4:3 resolutions except for 4k/UHD (native). I was using 2,560 x 1,440 but after upgrading was suddenly UHD, so I checked display settings to change back and the only options shown are 4:3. Can be overridden but something is wrong with the display detection all of a sudden.

MSI GS63VR Laptop with 4k display latest arch x64 clean install 4 days old with just base, multilib, base-devel, and KDE.

Any ideas? The only packages upgraded were Linux Kernel 4.10 from 4.9 including associated stuff like nvidia/glibc but that's really it. Doubtful to be nvidia as that's off by default/intel card is default and being ran. Modeset is just not correctly detecting resolutions as it did yesterday/pre-upgrade.

Also noticed this update even though a minor bump removed mesa-libgl, unsure if that has something to do with it? Any ideas as to gathering more information or a potential fix? I can override but rather not rely on that obviously, thanks!
