Summary0000494: madVR crashes with Intel HD Graphics 520 with driver version
DescriptionUsing madVR with MPC-HC and Intel HD Graphics Driver on a Notebook with Intel HD Graphics 520 works fine.

After updating to Intel HD Graphics Driver running any video seems to causes critical graphics issues (severe system-wide graphic errors, system lockups and complete system failure (i.e. automatic reboot or completely unresponsive requiring a hard switch).

Going back to the previous driver version solved the issue again.

So why are you reporting this to me and not to Intel? ;-)

Because you might know what's wrong and how/where to report it...

If you think it's an Intel issue I'd be happy to report it there (some pointers where to turn would be welcome), but I'm not sure if they'll even be willing to support me (as I'm basically forced to use Lenovo's OEM driver on my system and the official Intel driver can only be installed via workarounds).

I've contacts to some Intel guys, but those only interested in HDR related stuff. Also, I don't really know where even "normal" users can report bugs. There isn't really much I can do at all. Since the problem doesn't appear to occur with Nvidia or AMD GPUs, or even other Intel drivers, everything points to the new Intel driver version you've installed.

Of course you could try to work around the issue, e.g. by trying to turn on/off some madVR options like "use D3D11 for presentation", or "automatic fullscreen exclusive mode", or by trying to reduce the number of pre-presented frames. But I don't know if any of that will help.

Ughh, after Microsoft force-updated my driver twice now (one after the falls creators update and once just for the fun of it afterward) I tried to deal with this again and it's still messed up...

Some new observations on hte issue:
- it's independent of exclusive mode (happens with MPC-HC windowed
- it's not happening always
- when it's happening
  * playback mostly fails to start,
  * madVR reports "resetting Direct3D device failed" and/or "creating dxva decoding surface failed"
  * my secondary screen (which is the Notebook display) but not my primary screen (which is an external monitor) gets completely garbled(graphics memory corrupted?) and sometimes one even sees how it becomes black from the top line-by-line; usually most of the display is black but a few distorted lines at the top which show something that is porbably supposed to be the desktop...
  * audio playback is influenced, too, and starts to crack like an old LP.

Life saver in these scenarios: Win+Ctrl+Shift+B (I think this restarts the graphics driver) which lets one resume working with the system...

I tried some things (enable/disable D3D11 for presentation, disable pre-presentation, change number of pre-presented frames, use separate device for presentation/DXVA) but nothing seems to help so far :-(

I'm really sorry that you have these problems, but since they all seem to be GPU driver problems, I don't have the slightest idea what I could do, so I'll have to close this bug report.

Hint: You can disable forced driver updates somewhere (don't remember where, Google should help).
