4 days ago I started to dig deeper into this issue, and here’s what I’ve discovered so far:
Not Triggering the Bug:
- It works fine as long as only the directional buttons are used, without engaging the pointer feature of the LG remote.
- It also functions properly with an attached USB controller (Xbox).
- Opening the stream overlay with the controller (LB + RB + Start + Select) does not trigger the bug.
Triggering the Bug:
- The bug occurs when mouse input is used during streaming (tested with a USB mouse).
- The pointer feature of the LG remote triggers the bug during streaming.
What I’ve Tried:
- I experimented with nearly all input options in various combinations, but there was no effect.
- I tested different streaming resolutions, including native 4K, in case it was a scaling issue with the absolute mouse feature, but it made no difference.
Observations:
After closing Moonlight, the TV does not completely bug out. Sometimes it becomes responsive again, even to the magic remote. However, the stuttering consistently reappears the moment I use the scroll wheel. As soon as the cursor disappears, the TV remains responsive as long as only digital inputs (LG remote buttons or gamepad) are used. I have QuickStart+ enabled. Powering down does not immediately resolve the issue. However, leaving the TV in soft standby (without a full power cycle) for about five minutes completely resolves the bug until it is triggered again in Moonlight.
I further investigated CPU usage before, during, and after the bug. Even during the extreme stuttering, the TV remains responsive on the SSH terminal. The results of the "ps aux" command showed no increased CPU usage associated with the bug. To confirm this, I triggered the bug and opened the "System Information" page in KODI, which has a CPU graph. Interestingly, when I used the scroll wheel on the remote to trigger the bug, the CPU load even slightly decreased.
The time it takes for the TV to become responsive again after using the scroll wheel varies widely; sometimes it becomes responsive again after a few seconds, while other times it takes half a minute. The entire situation strangely reminds me on the behavior of a system that is running out of VRAM or maxing out the GPU. Unfortunately, I have no knowledge of how to debug GPU issues or how to check VRAM/GPU load.
