[Bug]: OBS Notifier does not show notifications on the first launch. Notifications are displayed outside the screen when the interface is scaled.

Commit or version

1.3.4

On which operating systems the error occurs

Windows

Issue description

OBS Notifier launches correctly and connects to obs-websocket, but no toast notifications appear on Windows.
obs-websocket events are received, but nothing is displayed in Windows Notification Center.

Environment

OBS Studio: 32.0.1 (64-bit, Windows)

OBS Notifier: 1.3.4

OS: Windows 11 Insider Preview, build 26200 (25H2)

What I Tested

Verified that Windows Toast notifications are working with PowerShell (Windows.UI.Notifications.ToastNotificationManager) → system notifications display correctly.

Verified that obs-websocket connects and events are received.

Tried re-enabling Focus Assist / Notification settings, no change.

Problem persists only with OBS Notifier.

Possible Causes

Outdated Notifier version: 1.3.x was designed for OBS 28–30, may not be compatible with OBS 31/32.

Missing AppID for Windows Toast: Windows 11 Insider (build 26200) requires a valid AppID for toast notifications. If no AppID is registered, notifications may be silently discarded.

Windows Insider restrictions: Newer Insider builds enforce stricter notification policies, which might break older implementations.

Would it be possible to update OBS Notifier to ensure compatibility with OBS 31/32 and newer Windows builds?

Steps to reproduce

1. Install OBS Notifier 1.3.4
2. Launch OBS Studio 32.0.1
   3.Verify that obs-websocket server starts(port 4455)
   4.Confirm Notifier connects successfully (log shows new client connected)
3. Trigger any OBS event (e.g., stream start/stop)
4. Expected: Toast notification should appear
5. Actual: No notification is shown

but no toast notifications appear on Windows.

The only Windows Toast you can get is a notification on first launch that says the program remains in the tray.

GPT? 😒

I don't think that's necessary, as the problem is most likely that you are using multiple monitors, possibly with different interface scaling in your Windows settings. Please try changing the Position offset settings in OBS Notifier.
This problem has occurred several times already. I had several fixes for this problem in my code, but it seems that it's time to replace WPF.

I even spent several hours creating the image and installing it on the VM. Everything works without any problems.

Even the only Windows Toast is displayed without problems.

Windows 10 also works fine with the latest version of OBS.

And that's how it breaks due to scaling (it's required to move the sliders by more than half):

yes sir,i did ask gpt for answers,coz i cant find any other solutions yet😂
and honestly i just have one monitor only,and still just nothing pop up as i turn on the OBS notifiier and connect to the server,even hit the preview button,nothing happens,anyway i think i will probably record a video to demonstrate what's going on

hit the preview button,nothing happens

I double-checked again, and the problem is identical on both Win10 and Win11. For me, it occurs when using scaling on the main monitor only. This needs to be fixed, but I can't promise anything.

its magically workin now

You probably accidentally scrolled through the settings page and touched Style Options with the wheel, and now your notifications are displayed on the left instead of the right.
