I recently got a RTX 2060 GPU and when I’m connecting/loading into a map, I see the cursor reset to the center, then reset back to where it was before. After hero select, the cursor stays in the center of the screen. After, the game stutters when ever I try to open the menu with the Escape key. Then it makes my cursor invisible.
There are some known issues with RTX cards, and a temp fix was mentioned here: "Render Device Lost" Fix for RTX - #236 by Drakuloth
If you’re using a Razer device, make sure you’re on Synapse Beta 3.
And if neither of those work, we can look at a DxDiag, or you can open a ticket. Blizzard Support - Obtaining System Files
