@Olina-Zhang, @LeafShi1 - could you please investigate if the same issue is present in native Win32 applications, either notepad, or create a custom MFC app with tooltips.

This should be a Windows issue, the same issue exists in notepad, File Explorer, MFC Application Image

@Olina-Zhang can you file an issue in the OS AzDO? We'll track it but I doubt there's much we're able to do.

Filed OS AzDO issue: 54688683. please help see if area path is correct.

@Tanya-Solyanik @merriemcgaw that OS AzDo bug: 54688683 was resolved "By design". Windows team told Tooltip behavior was intentionally changed years ago for accessibility reasons. If this appears to not be in compliance with WCAG 2.1 Tooltips behavior, let them know. If that's the case, for the Winforms tooltip control, it conflicts with the setting of tooltip's AutoPopDelay property obviously on Win11.

Hi @Olina-Zhang I misunderstood your bug report, yes this is "by design". The default AutoPopDelay had been overwritten on Win11 - the tooltip is dismissed by user action only. If the user changes AutoPopDelay to a non-default value, then that new delay will be applied to the tooltip - try setting it to 1000 for example

I'll reuse this issue as a reminder to update the docs

It does, and we need to reset the AutoPopDelay to a non-default value on Win11.
