Wallpaper thread crash: Cannot access a disposed object. Object name: 'Process'.

[meekah7]

Describe the bug
I have the Matrix HTML/JS wallpaper on 2 screens, and when running a game in fullscreen after a while sometimes the wallpaper takes up both screens, although not animated anymore. After Alt-Tabbing to get rid of the wallpaper, the desktop wallpaper is just black.

To Reproduce
Steps to reproduce the behavior:
Sadly I'm really not sure what exactly causes this behavior.

Desktop (please complete the following information):

• Edition Windows 11 Education

• Version 21H2

• Installed on ‎19.‎04.‎2022

• OS build 22000.675

• Experience Windows Feature Experience Pack 1000.22000.675.0

• The Matrix HTML/JS wallpaper, which I slightly edited. The biggest change would probably be the 25ms iteration speed instead of 50ms. script.js.txt

Additional context
The GUI for managing the wallpapers seems to work normally.

Looks like the browser crashed already and Lively is failing to communicate with it, I can't reproduce it on my system (nvidia).. could be amd gpu driver and CefSharp related.

What does the CefSharp logfile say?
%LocalAppData%\Packages\12030rocksdanister.LivelyWallpaper_97hta09mmv6hy\LocalCache\Local\Lively Wallpaper\Cef

Here's the single file I found in the directory you provided:
logfile.txt
Also, I am using an AMD CPU and GPU, so the drivers being an issue might be true. I'd be happy to work with you to resolve the issue with AMD drivers if you need me to test something on my hardware.

Hello, same issue with me.
Also full AMD and dual screen config.

Inside cef logfile, there is only 1 line of log... and it seems the end of the line is missing^^

I am switching to WebView2 in the future if things go according to plan.

There is a build of WebView2 for installer version of Lively if you want to test:
https://github.com/rocksdanister/lively/wiki/Web-Guide-I-:-Cef#webview2-microsoft-edge

but only url wallpapers work for now until the till this update MicrosoftEdge/WebView2Feedback#1825

I think I haven't had any issues in a while anyway. Not sure if it was an update of your software or a driver update, or maybe even just luck.
