enricobuehlerandClaude Fable 5 5e088af7ed fix(pf-win-display): unpin mode indexes on paths the CCD isolate deactivates
Field report: with Exclusive Topology, the physical monitor sometimes stayed
lit — every isolate attempt re-committed and failed SetDisplayConfig with
0x57 ERROR_INVALID_PARAMETER. Clearing DISPLAYCONFIG_PATH_ACTIVE alone leaves
the deactivated path's source/target modeInfoIdx pinned to the queried mode
entries, and per the SetDisplayConfig contract a path being turned off must
have BOTH mode indexes set to DISPLAYCONFIG_PATH_MODE_IDX_INVALID; some
driver/topology combinations (notably when the doomed path shares a source
with the kept virtual path) reject the supplied config outright, so the
retry loop could never converge.
