Before opening a ticket, please run through the following troubleshooting steps to help with your issue:
1. Update your Graphics card drivers
Please check that all Windows updates have been applied and that all of your system drivers are fully up to date.
Updating drivers for your graphics card and some peripherals isn't possible through the automatic Windows Updater & must these be acquired by the manufacturer's website.
For NVIDIA cards, you can get the drivers at www.nvidia.com and for ATI cards at www.amd.com. Drivers for Intel HD GPUs can be found at www.intel.com.
If your issue persists, try to reproduce the problem again and provide us with the information when and how it is happening. You will also have to provide a system report in the form of a DirectX diagnostic when contacting our support team which you can do below.
2. Turn off any background DVR recording
On some systems, it may be the case that your game is being recorded in the background by Xbox Game DVR or NVIDIA shadowplay.
This can be disabled individually in each program by following these steps:
While in-game press Windows + G to bring up the game bar.
With this showing, you should be able to select the settings "Cog".
From here please uncheck "Record game in the Background" as shown below

To turn off Shadowplay you will need to open NVIDIA GeForce Experience.
With this open please click on the settings "Cog" in the top right.
Click the toggle to disable the share feature.
