Research direction

No source file, test, or entry point is identified in the report. Begin by reproducing the tab-bar flicker in Windows Terminal 1.16.2642.0, especially across focus changes, and use the attached recording and reported environment as reference. Done means the tab bar remains stable during normal use and focus transitions.
