Hello Edie Ritter
Welcome to Microsoft Community to post your concerns about split screen.
Generally speaking, there are one ways to get rid of a split screen in Windows 10/and Windows 11
- Navigate to Start>>Settings>>System.
- In the left navigation pane, click on Multitasking.
- In the right pane, under Snap Windows, change the value to Off.
Turn off these values to turn off the Split screen function. In addition, what puzzles us is the "Going to shape" you mentioned. Could you please describe in detail whether it refers to any specific function that not work for you.
Best regards,
