[Issue]: Video decoder crashed on TCL 55C6K when TV system overlay (volume/menu) appears during streaming

Describe the bug

Moonlight crashes with a "Video decoder crashed" error (device incompatibility message) whenever a system-level
overlay renders on top of the video surface during streaming — this includes the TV's volume OSD, the controller's
guide/home button, or attempting to switch apps without ending the session. In most cases this requires a full power
cycle of the TV to recover; occasionally it shows the error dialog and Moonlight closes on its own.

Steps to reproduce

1. Start any stream from Sunshine.
2. While actively playing, trigger any of: pressing volume up/down on the TV remote, pressing the guide/home button on
   a connected gamepad, or trying to switch to another app without ending the session.
3. The video freezes, and either the TV becomes fully unresponsive (requiring a power cycle) or Moonlight shows "Video
   decoder crashed" and closes.

Affected games

Occurs across every game tested so far. I have not yet specifically isolated whether it also occurs streaming a plain
desktop/Steam Big Picture session (happy to test this if useful).

Yes

Moonlight adjusted settings (please complete the following information)

Tried forcing codec to H264 and to HEVC (both crash identically), adjusted bitrate between 40-70 Mbps, confirmed HDR
is disabled, updated Moonlight to the latest available version — none of these prevented the crash. The one change
that reliably prevents it: enabling the on-screen performance stats overlay

Additional context

On-screen stats confirm the decoder as c2.mtk.hevc.decoder, confirming a MediaTek chipset. This may be related to
issue #1601 (same "Video decoder crashed" error on a TCL Smart TV Pro, also Android 14). Key finding: enabling the
on-screen stats overlay is 100% reliable at preventing the crash — tested over a 2+ hour session with repeated
volume/guide-button triggers and zero crashes. My guess is that rendering the stats forces Moonlight into a different
video rendering path (GPU-composited rather than a dedicated hardware overlay plane), which is more tolerant of
concurrent system UI overlays. Happy to help test debug builds or provide further logs.

No source file or test is identified. Start by reproducing the crash on the TCL 55C6K with volume or guide overlays, compare the behavior with and without the on-screen stats overlay, and review related issue #1601. Done means overlays no longer crash the decoder without requiring the stats overlay, with useful logs captured for validation.
