Comment 3 Daniele Viganò 2017-01-15 10:57:24 UTC
This change makes some resolutions unavailable on my laptop with a 1920x1080 panel and Intel HD 4400.

After the upgrade all 16:9 resolutions (a part from 1920x1080) disappeared, like 1600x900 that sometime I use.

Downgrading to 1.19.0-0.3.20161026.fc25.x86_64 everything is working as expected.

JFTR , in Fedora 25 I'm tracing a long stand bug and seems xorg-x11-drv-intel-2.99.917-26.20160929.fc25.x86_64 is the problem , it some circumstances system slowdown a lot and is impossible to work, laptop gets very hot, processes take 100% of CPU and no explanation for that, after switch to modeset i.e. dnf remove xorg-x11-drv-intel . The laptop seems that get back to normal i.e. no processes taking 100% of CPU etc etc 

Also sometimes I got a little screen corruption specially on "GTK+ applications in KDE" and seems is also xorg-x11-drv-intel fault this happen since F23 or so .

So in conclusion I would recommend revert the fix in this bug report, should I reopen this ticket ?
