"Find on Page" in Chromium Edge is not working sandboxed on Windows 11

Hi @DavidXanatos

I updated to Windows 11 on one of my machines last night, and there's a problem with the function "Find on Page" in Chromium Edge when running Edge under Sandboxie 0.9.8.d. I then updated the machine to Sandboxie version 1.0.0, but the problem persists in this version too. As I only just updated to Windows 11, I'm afraid I can't tell you which version of Sandboxie or Edge this became a problem. I'm running Edge 96.0.1054.29.

The problem does not occur in my Windows 10 machines running Edge under Sandboxie.

To reproduce in Windows 11, go to the 3 dots (settings and more) in Edge and click on Find on Page. Unsandboxed - the wee find bar with the arrows appears as it should, but sandboxed - it's invisible. If you mouse over the general area you'll see a sandboxed yellow border appear, but the contents are invisible rendering it unusable. It's not a problem on FF, Chrome or Brave though - just Edge. I tried changing colour schemes of the browser and using with/without an external monitor, but no change.

Here are some screenshots of with Sandboxie and without:

I would appreciate if someone could make available a trace log about this issue for analysis, see: https://git.io/JDIhI

this issue will be resolved using an experimental new feature, to enable it add EnableWin32kHooks=y to your sandboxie ini and reload the driver or reboot.
