I changed the sequence settings from 1920 X 1080 format to a square 1080 X1080 format. The reason is I wanted to post the video on instagram.
This created a problem: a white flickering line across the right hand corner of the program monitor on certain clips. This line does also appear in the exported video.
- If I change my sequence setting back to 1920 X 1080 this problem disappear.
- In my time line, I have added adjustment layers above all clips. On the adjustment layers I have added the Lumetri Color fx for color correction.
- Flickering appears only when these adjustment layers are enabled. However, some clips do not get any flickering, even when adjustment layer is enabled.
- If I apply the Lumetri Color fx to the video clip instead, and disable the adjustment layer, the flickering goes away.
- However, if I then replace video clip with after effects compostion (I want to add some moving text fx to my video) the flickering comes back.
- I have tried resizing the clip to 300% to ensure the clip fills up the whole program monitor.
- on my time line I have MPEG:s from a DJI Phantom 4 (23,976 fps), a Canon xa10 (25 fps) and a GoPro Hero 3 (25 fps)
- the white line appear on all three kinds of footage, but not on all clips in the timeline. To me it seems random which clips have the whiteflcikering line and which have not.
- i use a MSI GS VR 7RF Stealth PRO Laptop.
- I have restarted the computer several times.

It´s a bug in the Lumetri color and should be fixed but probably not in CC2018.
For me, resetting the Blacks and the Whites in the Lumetri filter fixed the issue. Or, turn off CUDA acceleration.
