NSWindow warning: adding an unknown subview

[probablykasper]

Describe the bug
Getting this error when opening devtools on macOS. The app doesn't crash. When resizing, the screen goes white.

To Reproduce
I only opened the devtools, not sure what else would contribute to this.

I have the same problem

[nothingismagick]

Thanks for the report. This is definitely not an issue in Tauri, but in WRY. Am transferring.

[wusyong]

Duplicate issue of #297

[probablykasper]

@wusyong I think I'll reopen this because it seems separate. This warning happens the first time you open the devtools, while #297 happens only when you resize the window while the devtools are open.

I have the same problem- with an additional crash reported in the logs after the warning:
