System-wide graphical glitch upon exiting fullscreen

I've encountered an odd error that happens occasionally, but often enough to be a bother. Somewhere in the region of 1 in 20 times I exit fullscreen. I play many fullscreen games -- it has never happened with any app other than Dolphin.

Upon exiting fullscreen, the entire system will show a weird blur or doubling effect. If I enter fullscreen mode again, the screen will cease output and remain so until a hard reboot. The same for if I try to change the resolution via the windows settings. This also occurs if I put the system to sleep and try to wake it up. It will sleep, and then wake up with a blank screen, and no peripheral activity (keyboard will remain off), requiring a hard boot. The system will also not shut down normally, it will remain stuck with a blank screen.

It has been happening for almost a year as far as I can remember. It happened today again and I was able to take a photo. I suspect it may be a driver corruption. I don't expect anyone to provide a fix, but I wonder if anyone at least has any tips for how to restart my graphic driver without a hard boot? I hardly ever shut down my computer, and usually put it to sleep -- so this issue requiring a hard reboot to resolve causes a disruption of the apps I keep open.

I've attached a photo I've taken with my phone

I have an nvidia 1080 GTX with the latest drivers. I've performed cleanses with DDU across several updates, and it has occurred for months across many nvidia driver versions.

I had been using the stable 5.0 release, but lately I installed the 5.0 -5634 developer release. It happens across both versions.

What backend are you using in Dolphin: OpenGL, D3D, or Vulkan? Does this happen on all backends, or just one?

Is your power supply properly hooked up to your GPU? Is your power supply rated to handle your CPU and GPU running at full load? Running your specs through a rough power calculation puts it at about 400W under full load, so that means you should be using a 55W 80+ Bronze power supply.

If it's not power related, it could be a component on the GPU is going bad, in which case you may need to contact the manufacturer/company you purchased it from.

An online wattage calculator with my full component list has my system at 477 W. I am running a 750 Watt Gold rated XFX PSU. It seems to be alright, but now that you've mentioned it, I will make sure my power outlets themselves have consistent voltage output. 

I have always used D3D and have never tried Vulkan. I have only brief dalliances with OpenGL due to the increased CPU usage. I will experiment more with different backends now that I know it may be a factor. It can be tough to pin down an issue that seems to happen of its own wit and produces no error logs that I can find. 

The reason I doubted a hardware error is I have never had issues with anything other than exiting fullscreen mode in Dolphin. It is only this action that produces an error. No other D3D game, nor even entering fullscreen mode. Although I will now add a component fault to my list of possibilities. Thank you.

If you're using a Nvidia GPU, OpenGL is a lot faster (when not using ubershaders). YOu may also want to do a quick Google search for the "DirectX web updater" to make sure all that display driver installing/uninstalling didn't break your DirectX.

If you can, you may want to do a clean install of Windows on a spare hard drive or partition, and see if that gives you the same issues you see in your current install, which can rule out something being messed up with Windows.

The only reason I mention component issues is that we have a GPU in a lab computer that will fail when doing specific graphics tests that are fine on other, similarly specc'd machines.
