Flickering cursor over a Button with ToolTip in the bottom right corner

Your video is just black for me.

Tootips have been refactored recently, can you still reproduce your issue in 11.1.0-beta2?

Your video is just black for me.

It's probably due to the 4K resolution. There is a very tiny Button in the bottom right corner. I probably should have reduced the resolution of my screen for the recording.

After short test: It seems not to appear with 11.1.0-beta2.

@CodeDevAM if 11.1.beta resolves your issue, this ticket can be closed. Please do us a favor and always test at least beta (even better nightly) versions before opening an issue, as many things are already solved in there. Thx.

The problem still occurs with 11.1.0-beta2.

I could reproduce the issue after pasting this grid into the Sandbox project:

  <Grid
  ColumnDefinitions="1*, Auto"
  RowDefinitions="1*, Auto">

    <Button
			Grid.Column="1"
			Grid.Row="1"
			Content="X"
            ToolTip.VerticalOffset="0"
			ToolTip.Tip="Clear completed, failed and canceled count"/>

  </Grid>

Note the custom VerticalOffset value.

It seems to be the same issue as one I recently worked around in #15312. At the very edge of a tooltip popup there is a region which sometimes counts as being over the popup, but does not have any hit test result. So we think there is nothing beneath the pointer end up opening and immediately closing the tooltip in a loop.

Workaround: move the cursor a bit so that the cursor isn't directly over the edge of the popup.

@CodeDevAM @TomEdwardsEnscape does it also happen in nightly?
