What is the cause of this small red icon appearing top left on my screen randomly during gaming?

I have an Asus ROG PG279Q monitor connected to an nVidia 1080 Ti card from EVGA, Windows 10 Pro, and an Asus motherboard.

Randomly, say once a month, I will see the icon below appear overlaid on my monitor (top left), about three times the height of the icon below the top of the monitor, then it will glide upwards and out of the top of the monitor, taking about 4 seconds all in all, when I play Starcraft II. It clearly is not generated by my monitor as I pressed PrintScrn to capture this image, meaning it was in video RAM.

What is causing this icon and what is the meaning? I cannot see that the hardware is overheating as I have a mighty liquid cooling solution.

I have a photo of the icon just cannot post images or links here?!

Hey there,

Does the icon look like one of these?

If you post your image on an image hosting website like imgur.com and then share the link here that should work. Make sure to either break the link with spaces or highlight the link and use the </> button so it will allow it.

Can you also post your DXDIAG so we can check that out?

  1. Press Windows Key + R.
  2. In the Run window type dxdiag and press Enter.
  3. In the DirectX window, click Save All Information.
  4. Name the file “dxdiag” and save it to your Desktop. Open the new dxdiag file with Notepad.
  5. In the posting section hit the </> button for “Preformatted text” then paste (Ctrl+V) the DXDIAG contents. That’ll make the information much more readable.

If you are unable to post this due to the length of the DXDIAG, please feel free to use pastebin.com and share the direct link with us instead. Use the </> button as well in order to share the link.
