downgraded back to 1.2.4 and still having the same issue, not sure if 1.2.5 maybe broke something?

The stream is failing because an unsupported display configuration is breaking the host's screen capture API.Client Request: Your streaming client (LG G5) initially requests a display mode of 3840x2160 at 120Hz. Refresh Rate Conflict: Your host configuration has the double_refreshrate workaround enabled. This setting modifies the request and tells the display helper to create a virtual display at an extreme 480Hz refresh rate (numerator 480000 / denominator 1000). Topology Rejection: The system cannot support a 4K resolution at 480Hz. When the display helper attempts to apply these settings, it triggers multiple ERROR_INVALID_PARAMETER and ERROR_GEN_FAILURE errors and fails to create the new topology configuration. Capture API Crash: Because the virtual display configuration failed and left the system's display state in flux, the desktop capture API (DuplicateOutput()) gets trapped in a failure loop with error code 0x887A0025. This specific DXGI error indicates that a display mode change is in progress or stalled, preventing the capture service from hooking into the screen. Session Drop: The capture service repeatedly reports that no displays were found after reenumeration. Without a valid display output to capture, the host sends a black screen and eventually drops the connection. Resolution StepsDisable the double_refreshrate setting in your host configuration. By turning this off, the virtual display will adhere to the client's original 120Hz request, allowing the topology to initialize successfully and the capture API to detect the display.

from gemini, nothing has changed on vibepollo end though

LG decoder has a lot of issues with 4k decoding. Try 3.6k 120fps hdr and tell me if these issues back again.

ok but it was running just fine up until last update which is strange why it started with 1.2.5.

will try your suggestion tomorrow
