MacBook pro with i7-4870HQ
They all sucked. Even the Kaby-Lake gen couldn't playback with the same symptoms as you. I'm sure an i5-6600K can play H265 in VLC or other software without any problem, even if the architecture doesn't optimize it.

All Nvidia 10-Series graphics cards, like 1070 and 1080, have hardware decoding support for HEVC 10-bit h.265, same with the new AMD GPUs. The new Ryzen processors have support for the codec built in too. Quik is just a sloppy program. The programers at GoPro are lazy. You have to use another editing program. You can verify the support yourself by loading up one of your videos in Windows Media Player Home Cinema. It kinda feels like Intel kicked GoPro some money to sell some processors, but they couldn't even get that right.
