Testcase Gist URL

N/A

Additional Information

I can't find any pattern in settings for these windows so far. They're secondary and tertiary windows of the application. For some reason the primary window renders without issue.

The issue also affects the taskbar previewer as seen here - the "Settings" window is not rendered. Checking window size/position - and re-centering the window make no difference.

I manually "bisected" Electron versions and arrived at 13.6.0 as the last known good version.

I feel all but certain the cause is #31550

Bump. I'm concerned about not being able to upgrade our project past 13.6.0 due to this issue.

@slapbox If this is caused by the PR you referenced, please try a newer version with the fix from #31768 (e.g. latest v13). Otherwise, please provide a repro fiddle.

@deermichel thanks for the update! This is indeed fixed in 13.6.9.

Great, thanks for the update!
