Hello Lea. Thank you for the reply.
The Fire HD tablet is set to its native resolution of 1280×800.
I’ve tried all of those things. I’ve tried 60 fps, then 30 fps. I’ve adjusted the image quality to low. I’ve changed the settings to 16-bit and 32-bit color. I’ve tried using a different USB-C cable and changed the connected USB-C port on my GPU and then to my motherboard.
The PC’s cpu usage isn’t high, the spacedesk process is using 0% when the issue happens.
None of these things did anything to change the the issue I described.
