⚡ Debounce continuous WindowSizePosLog.ini writes to drastically reduce Disk I/O

[Ven0m0]

💡 What:
The optimization changes the IniWrite operation that previously occurred on every window drag/resize loop execution into a deferred, debounced disk write operation.

🎯 Why:
The performance problem is excessive disk I/O when tracking window positions. The MonitorWindows loop runs every 350ms. When dragging a window, a single IniWrite was called on each loop iteration, leading to hundreds of unnecessary synchronous writes. The final resting position is all that needs to be logged.

📊 Measured Improvement:
Dynamic execution of AHK benchmark was not performed since the environment lacks Wine (autohotkey command is missing). However, mathematically, a 10-second continuous window drag operation that previously caused ~28 individual disk I/O write operations (1 per 350ms) now performs exactly 0 disk writes during dragging and 1 disk write after 1000ms of inactivity, resulting in near 100% reduction of blocking operations over that timespan.

Pull request overview

This PR reduces disk I/O in the Window Manager GUI script by deferring IniWrite calls while a window is actively moving/resizing, then writing the final position after inactivity.

Changes:

• Introduces LastSaved/PendingWrites maps (case-insensitive) to track last position and pending debounced writes.
• Adds a ProcessPendingWrites timer to flush queued INI updates after an inactivity threshold.
• Updates SaveCurrentWindowPosition() to queue writes instead of writing immediately.

[Copilot]

ProcessPendingWrites() calls IniWrite() without any error handling. If the INI write fails (file locked, permission issues, etc.), the timer thread can throw and potentially stop processing future pending writes. Consider wrapping the write in a try and only removing the entry from PendingWrites after a successful write (or keeping it queued to retry).

Suggested change

	IniWrite(currentValue, A_ScriptDir . "\WindowSizePosLog.ini", "Process Names", processName)
	}
	keysToDelete.Push(processName)
	try {
	IniWrite(currentValue, A_ScriptDir . "\WindowSizePosLog.ini", "Process Names", processName)
	keysToDelete.Push(processName)
	} catch e {
	OutputDebug("WM.ahk: Failed to write INI for process '" . processName . "': " . e.Message)
	}
	}

[Copilot]

The debounce behavior here can exceed the stated 1000ms: the timer runs every 1000ms and you also require >= 1000 elapsed, so the actual write can happen ~1000–2000ms after the last change depending on timer alignment. If the intent is “write 1000ms after inactivity”, consider using a shorter polling interval (e.g., 250ms) or switching to a one-shot timer that gets reset on each change (e.g., schedule ProcessPendingWrites with a negative period on updates).
