The report mentions lag, idle disconnects, reconnect freezes, and a screen-black-state freeze, but names no files, tests, or entry points. Start by reproducing the idle disconnect and screen-state cases on the affected version, then identify the relevant terminal or connection logs; done means both freezes are fixed and the initial-version behavior is understood.
