There are no issues reported about this type of files. Could you please give me more details about the issue and your system configuration?
Apologies for the poor quality photos - these are photos taken on my phone of the TV screen. It is much more apparent in real life.
This occurs on every x265 file i've thrown at the NUC and has also happened on both NUCs i've owned (returned the first after whea error).
NUC6i5SYH, 500gb samsung 850 m.2, 2x8gb KIngston HyperX. All files played through kodi on windows 10 using hardware acceleration. When acceleration is turned off and decoded by software the problem doesn't occur.
Please tell me if you are using the latest BIOS version 0039 and the latest Chipset, Management Engine driver and Graphics driver.
Also, let me know if problem is happening with any other media software.
I fixed the problem...
The problem is caused by the Intel Iris graphics program. Load up the program and turn off all the video 'enhancements' there are about 5-6 options. Once I disabled all of them the problem went away. I couldn't be bothered going through them one by one to see which setting is actually causing the problem.
It's pretty bad that the defaults settings are causing this issue. Maybe intel should disable all these 'enhancements' by default.
Even with these disabled, the blocks go away but the picture is not quite as good as when hardware acceleration is turned off and it is decoded by software (only very slightly - but still noticeable if looking). Hopefully as the drivers mature they will equal each other.
Is there a way to uninstall this software completely but leaving the driver in place?
The graphics control panel comes together with the driver; it is necessary to use both at the same time.
There is an option to save memory; if you erase some files using the steps below:
You may find this setting in the "System Configuration Utility":
Start > Type "msconfig" > Startup tab > Uncheck "hkcmd", "igfxpers", "igfxtray"> Apply, then restart your computer.
