App version

3.8.2

Windows version

10 Pro 21H2

Steps to reproduce

1. Do not skip displayed simplewall's Alert dialogs - don't press Allow, Deny, Next, or any other button, just ignore dialog.
2. Wait hour or more to more alerts be displayed in this dialog

Expected behavior

New Alert dialogs are displayed as earlier, with option to Allow, Deny or skip (Next). NOTE: before update to 3.8.2 in all earlier versions from about 2-3 years timeframe all works as above.

Actual behavior

After some time and displayed alerts in dialog it appears empty. Nothing is visible. (see attached image)

App's context menu in Systray is empty too. Also exit confirmation dialog - just empty window frame displayed fullscreen, but pressing blindly Enter from keyboard closes simplewall.

Additionally mouse cursor sprite gets corrupted and refreshing display GUI elements in other apps appears glitched. It backs to normal after exiting or killing simplewall.

Logs

No response

It seems that it was some "hanging in background" system update setup problem. After restarting Windows few times and doing some cleaning up it looks that problem gone. Closing issue at the moment.
