Sorry, this is gonna be a messy post..

Display distortion? USB 3.0 cable?

The only plausible thing I can think of, off the top of my head, is USB 3.0 2.4Ghz interference.

If you've never heard of this and happen to have a USB 3.0 device like a flash drive and a wireless mouse which uses the 2.4Ghz frequency, you can easily test this and see it for yourself.

Just plug the flash drive and the wireless dongle to USB 3.0 ports next to each other.

Try moving mouse. It should be ok.

Then try writing or reading data to/from the flash drive. For example you could run crystaldiskmark on the flash drive or move a large file on to the flash drive.

Now try moving the mouse again when the benchmark or file transfer is in progress.

Laggy lag lag. Hilarious eh? Oh, don't move your mouse miles away so you can easily stop the benchmark, otherwise you'll be there watching the whole benchmark or file transfer while your mouse is almost unusable.

The display runs off of the battery so the higher voltage that the charger supplies (max 12V, read below) should have no effect on the display.

The battery is a buffer in between the mains and other components which draw power from it. Just like an online UPS.

There could possibly be some ripple voltage (or other kind of electrical "noise") originating from the mains voltage or from some other power device plugged in to the same circuit or from the charger itself if it's a badly designed electrical product but I would highly doubt that.

But even then, if there's some amount of ripple in the output voltage of the charger, it should easily be dampened by the battery itself and by the battery charging circuitry inside the phone.

I have no freaking clue how QC 3.0 works or rather have something I could easily put into words/post that's solid and intelligible.

One of the reason is that Qualcomm's QC is a proprietary thingymagic so I yeah..

But.. Anyway..

There is no problem here with either

a) the cable

b) or the QC 3.0 voltages

If a cable is up to Type C spec > then it is up to Type C spec.

Also didn't I just few hours ago type a kind of a rant that told you: connector/cable standard =/= technology standard?

So no, they haven't bundled a "2.0" cable with the phone which would "limit the phone to charge like a QC2.0 instead of QC3.0".

If the cable is up to Type C spec then it will just work like anyother cable that's up to Type C spec.

So I'm just gonna drop these here. You can probably connect the dots yourself, but I'm gonna highlight the important bits anyway and add some commentary. Yup, I knew this post would be messy before I even started.

"allows your device to determine"

"offers ... from 3.6V to 20V.

Just because a charger COULD output for example 5V 3A, it does not mean that the charger will just pump that amount of current out, nor does it mean that a device which is specified to only draw 5V 1A would charge any faster on a 5V 3A charger compared to a 5V 1A charger..

Same goes with QC 3.0. Just because the doodah ALLOWS a range of 3.6V to 20V to be used does not mean you SHOULD use say up to 20V voltages.

Example

http://www.aukey.com/product/pa-t9-chargers-qc3-0

So tl;dr just because the max voltage/amperage is 12V/1.25A does not mean the charger and/or phone isn't charging like a QC 3.0.

QC3.0 just "allows" or "offers" the maximum 20V level in it's spec if some device wants to use that high of a voltage.

Also there's a charger size factor in here and also inside the phone with it's battery charging circuit.

Adding more voltage levels means bigger circuit.

The only worrying bit of information is this.

Copy paste from Rapid Charger 2.0 specs?

Could very well be, it's almost exactly the same.

Well how about this then?

"We hitup Jeff Gordon on twitter but he hasn't responded. He did make a statement that he saw 12v, 1.2a on QC 3.0"

Well, it's not gonna draw more higher voltage than 12V because it's not designed to draw higher than that. See the Aukey charger..

Also it's not gonna draw more than 12V 1.2A if the phone decides "I'm now going to charge at 12V 1.2A".

Also how did he measure that? What was the equipment he used? When was it calibrated?

If HTC says "Qualcomm® Quick Charge™ 3.0 technology built-in" with the Rapid Charger 3.0 features, I'm going to believe HTC.

We'll know 100% sure when the Qualcomm certified devices/accessories list is updated.

It's updated monthly and last update included 3/2016 devices/accessories and was uploaded April 2nd so there you go, go look at the list on week 18. I have a feeling the HTC 10 and it's Rapid Charger 3.0 will be there on the list by then.

Well it's not copy paste, the output voltage/amperage numbers are the same on the actual charger.

Here's a German unboxing in 4K.

Screenshot from it which I flipped upside down.

But it looks like it has all the logos and QC 3.0 logo / text so it should be certified.
