           Summary: [i915] 4.6.7 and beyond causes screen flickering
                    whereas 4.5.5 works fine.
           Product: DRI
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW

Hello. I reinstalled a fresh Fedora version 24 64 bit from their website after
formatting the previous system since I had an issue where a dnf update caused
heavy screen flickering on my computer.

The formatting fixed the issue but as soon as I updated through the command
sudo dnf check-update; sudo dnf update -y and restarted the issue came back. A
restart and a launch into the backup kernel version 4.5.5 fixed the issue
again.

I will continue to try to find this issue because it is borderline unbearable.

My computer specs are as follows:

Lenovo Thinkpad Edge E540 using an Intel i915 video card and a Geforce GT 740M.

Again, this is a completely fresh install compared to nothing but a dnf update.

As far as I know this started the very first kernel update after installing
Fedora 24. I think it was 4.6.7.300 or something like that.

As of today I'm still using the old 4.5.5 kernel since thats the only one not
causing screen flicker.

I have installed the latest kernel (4.7.3) and tried that and to no good
effect.
