LA4-6620: Deltacast Interlaced Signal Handling

FHD60i video sent via FLEX HMI-10 and GWY316-4 displayed as a halved texture in LA due to improper interlaced field handling. Enable Field Merging to resolve. Set stream property VHD_CORE_SP_FIELD_MERGE to TRUE, as recommended by Deltacast.

Status: Done

Other Upgrades

There are 2 new upgrades in this epic.

LA4-6623: Hide Bugsplat With A Launch Argument

Added a launch argument to control BugSplat behavior in sensitive scenarios. When -no_bugsplat is present (via command line or options.ini), the app will either fully disable BugSplat or suppress only the BugSplat popup while still writing crash dumps to the crashDumps folder. Behavior depends on BugSplat SDK capabilities. This provides a cleaner user experience without losing critical crash diagnostics where supported.

Status: Done

LA4-6441: Mute All Autoblend Nodes

Resolved an issue where enabling “Mute all AutoBlend nodes” showed a warning but still output a masked texture from AutoBlend to Texture Blend. The mute action now correctly bypasses the blend mask, passing through unblended textures as expected.

Status: Done | Requesters: RIG
