Recursion overlay freezes after a while

[CptLegshot]

After long moments of inactivity overlay stops working, almost as if it goes into some kind of sleep mode. If i alt tab to the program itself everything works except session timer which is frozen too.
Eventually it starts working again after i've pressed the overlay hotkey or alt tabbed.
If i press the overlay hotkey very often it never freezes. Only freezes if i haven't pressed the hotkey in a while.
Seems to freeze sooner when performance is lower (big battles).
Not a recent problem, had it for a long time.

I wanted to try legacy hook but that crashes the game.
