Strange lines on screen only in Time Machine

Thanks for that elaboration!
Interestingly, this issue does not occur when using a non-retina resolution, as another user pointed out earlier.
And yes, even with the latest update which has been released yesterday, nothing has changed. Probably we have to sit out another full iteration, as this issue is not considered to be extremely important.
Same here. New 2016 15" MBP, 16 ram, 2.9 ghz, 1 tb ssd, 460 4gb gpu. I've only seen vertical lines in Time Machine so far. I'm hoping for a quick software fix, but if it doesn't come soon I may consider returning the unit. I spent too much on this thing to get stuck holding what could turn out to be hardware related.
This is ridiculous and constitutes a major defect - together with some other issues referred to on these boards. Apple is doing nothing about this despite informing me it is with "engineering". I have raised this with Apple since October 2016 and there is no resolution in sight. I have written to Apple Australia (by post as no email is available!) and demanded a full refund.
Keep submitting feedback via this link and be hopeful for a fix!

What is NVRAM?
A small amount of your computer’s memory, called “non-volatile random-access memory” or NVRAM, stores certain settings in a location that OS X can access quickly. The settings that are stored in NVRAM depend on the type of Mac you're using, and the types of devices connected to it.
Information stored in NVRAM can include:
- Speaker volume
- Screen resolution
- Startup disk selection
- Recent kernel panic information, if any
If you experience issues related to these features, you might need to reset the NVRAM on your computer. For example, if your Mac starts up from a startup disk other than the one you've specified in Startup Disk preferences, or if a question mark icon appears briefly when your Mac starts up.
It's still the same. But in ColorSync Utility i have these errors (I don't know of this is related in anyway with topic, but I'll post it here):

chris,
Could this be the beginning of the graphics card failing? I had an iMac 24", a few lines started, then many lines with an outcome of it not working at all (lines).
Just a thought.
@JayB - Changing user didn't work. I'll try reinstall, but I don't have the time for this at the moment to do that 🙂
@Garrat - it would be a shame if it is a graphic card because it's only a few months old mac.
