Okay, so I've been having a persistent issue with my PC, where Intel HD Graphics seems to be misbehaving, sometimes even in basic Windows desktop. After running into a dead end trying to solve the issue, I asked the computer store where I bought the mother board for advice. They directed me to this forum, telling me it's a known issue, and it might not have a solution at all.
So, that gets me here. I have a fair bit of disbelief into the idea that this issue does not have a solution. Surely there must be configurations where Intel HD Graphics 530 works just fine? Otherwise I'd greatly question the rationality of the product.
But let's see where we get here. Here's all the info of my situation:
Answers (N/A if not applicable)
Provide a detailed description of the issue
The screen becomes corrupted within seconds or minutes from launching certain apps. Light games (like "Inside") are a good example, or just launching Google Maps (reproduces with Chrome, Edge and IE) is enough to make the screen go haywire. This is the most trivial way to reproduce the issue. Attaching a screenshot from Google Maps as a reference. Basically anything that stresses the iGPU at all seems to make the system more or less unstable, including watching a video.
Occasionally I can see the issue on plain Windows desktop too, but with the current drivers quite rarely. With some driver versions I get constantly corrupted image even on desktop.
When this happens, the graphics driver will also become prone to crashing completely. Usually it can recover, but sometimes it goes into full blue screen situation.
Also it is clearly not a cable issue as I can see vertex explosions; this does not occur inside an HDMI cable. (See the image from Google Maps)
And I have setup every performance setting I can think of to default (Just about everything in BIOS to default basically), so there should not be any potential OC problems (but please review the logs I'm attaching in case you can find something).
Intel Processor Diagnostic Tool tests all pass with flying colors. I will attach the logs.
I have tested with several different Intel HD Graphics driver versions. Currently I am running the latest driver from Asus own support web site, which seems to be the most stable so far. Still far from acceptable.
I have tested with an external video card, and with that the problem goes away instantly.
Also the problem goes away if I set the display refresh rate to 30 Hz, at least with Google Maps. But that is obviously not an acceptable solution. NOTE: This could imply a problem with the HDMI cables, but the character of the corruption does not support this idea. See attached screenshot.
Please place an X to the right of the option showing how often you see this issue using specific steps. (Ex: 'Every few times a game is started it flickers.' <- This would be "Often")
Always (100%): Extremely easy to reproduce within seconds with Google Maps.
Brand and Model of the system.
Asus Z170-A Motherboard
Intel Skylake HD Graphics 530 (i5 6600k)
Hybrid or switchable graphics system?
Nope, only iGPU
Make and model of any Displays that are used to see the issue (see note2 below).
Through DisplayPort and HDMI adapter. But as stated before, the character of the corruption is clearly occurring the 3D rendering as well, not just in the erratic patches in the image, so it cannot possibly be caused by the cable or the adapter.
How much memory [RAM] in the system (see note2 below).
8 gigs DDR4 running at stock clock rate. XMP disabled. Memory modules tested and fully working.
Provide any other hardware needed to replicate the issue.
Hardware Stepping (see note1 below).
Operating System version (see note2 below).
Windows 10 64-Bit
VBIOS (video BIOS) version. This can be found in “information page” of CUI (right click on Desktop and select “Graphics Properties”.
Graphics Driver version; for both integrated Intel and 3rd party vendors (see note2 below).
SW or Apps version used to replicate the issue.
Google Maps on Chrome, for instance.
Single display, clone, or extended (see note2 below).
Display resolution & refresh rate setting of each display (see note2 below).
3840x2160 or 1080p @60 both replicate the issue. Lowering refresh rate to 30 Hz or below removes the problem.
AC or DC mode, i.e. is power cable plugged in or not?
Yes, this is a desktop PC.
How to repro
Please provide steps to replicate the issue. These steps are very crucial to finding the root cause and fix.
Okay, so there you have it, hopefully I remembered to mention everything. I have tried quite many things to solve this but nothing seems to be biting.
