Recording a single window doesn't have this issue. ### AMD/Intel root permission When recording a window under AMD/Intel no special user permission is required, however when recording a monitor the program needs root permission (to access KMS). To make this safer, the part that needs root access has been moved to its own executable (to make it as small as possible) and a GUI sudo prompt is shown to run this executable as root.
