"Recording kept showing static screenshot instead of real-time actions."
"The recording displayed a static image rather than capturing real-time actions."
You can only record the content within a specific window, which may include multiple tabs, if you choose the recording mode of Desktop -> Window. Therefore, if you navigate away from that window such as navigating to another Window or App/Software while recording, the recording stream will end the screen will appear "stop" in the recorded video.
To avoid interruption, do not navigate away from the window being recorded when using the Desktop -> Window recording mode.
If you choose the recording mode of This Tab, you can navigate to other tabs or windows without affecting the recording on the original tab, because the recording can only focus on the content within that specific tab.
