I wanted to provide a step by step guide as to howto fix this issue for anyone who does a search and has this issue.

I originally commented this in another thread but I felt it may possibly get lost or wouldnt be easily found so hense I am taking my original comment and turning it into a standalone thread that hopefully may be stickied.

I would like to point out this issue typically is because youre using Win 10 default system settings related to gaming.

the issue probly does not occur if youre using an older OS

---------------------------------------

Now for my guide.

Step 1: Click Start
Step 2: Open Settings and if you cant find it in the Start menu then just do a simple search for it
Step 3: Click System in the Settings menu
Step 4: in the search box of that menu type and search for Game bar settings
Step 5: Change its setting from being on to off and I would recommend unchecking the option for "Open Game bar using this button on a controller" too

---------------------------------------

And that is how you get rid of the desktop mouse displaying ingame and messing your gameplay up
