Does this explain your situation?
Use these checks to interpret the source. This is a reading guide, not a device test or a vendor diagnosis.
Match the streaming path, not just the app name
An OBS problem is not enough to identify this issue. Look for NDI feeds between PCs and the documented lag or uneven audio/video. If you are troubleshooting local capture or a different transport, this record does not establish the cause. Keep the symptom match separate from the diagnosis.
Source: MicrosoftKeep the originating KB and the fixing KB separate
KB5063878 identifies the documented starting point on Windows 11 24H2. KB5065426 identifies the historical resolution. The useful question is whether your applicable cumulative update includes that resolution, rather than whether you should install an old KB by name. This record does not identify the latest update available today.
Source: MicrosoftDo not carry a Windows 11 fix across to Windows 10
The source lists Windows 10 versions among the affected platforms, but this record links a fixing KB only for Windows 11 24H2. An affected-platform entry and a verified fixing-update entry are different claims. Use the guidance for your exact Windows version; the Windows 10 fixing KB remains Unknown here.
