There's a bug that creates a heavy lag on wake

[Gnio]

Hi everyone,

I've been using this app for many years, and I recently discovered an issue that happens on every Windows 11 laptop I've tried. Whenever the device wakes from sleep, the system lags heavily for about five seconds. I always assumed it was just Windows 11 acting up, until I tested further and isolated it to this software.

I'm not a coder, but I cloned the repo and asked an agent to locate and fix the bug. It did, I built a new executable, re‑installed it, and the issue disappeared. So it seems the fix was straightforward.

Is there a way for me to share this here? What’s the best way to communicate the fix? Should I open an Issue and include the details from my cloned repo?

For reference, the cloned repo is here: https://github.com/Gnio/Windows-Auto-Night-Mode
And these are the changes (i think): master...Gnio:Windows-Auto-Night-Mode:master

Thank you, love you all, be kind.

This is the agent's comment of the fix:
Fix wake-from-sleep lag by offloading theme switch to background thread.

I haven't notice any issues since I installed the new version but not usre if the fix applied is good, just know that it works

you can submit a pull request for this and we will merge that in. If running the time sync not on the main thread resolves that issue that's great.

For running RequestSwitch I'm not really sure how that resolves your issue as the actual theme switch is already running in a background thread (see here)

Windows-Auto-Night-Mode/AutoDarkModeSvc/Handlers/IThemeManager2/Tm2Handler.cs

Line 180 in c83a142

public static (bool, bool) SetTheme(string displayName, string originalPath, List<ThemeApplyFlags> flagList = null, bool suppressLogging = false)

Could you check if removing this makes a difference?

Because logically from what I know it shouldn't.

i will try this and revert

I'll wait for your update on this before we release 11.1 so we can get the fix in with the upcoming stable!
