I have a very strange behavior on my Tooltips that are associated with dropdown items.
I've posted a video because it's easier to see https://imgur.com/a/RxFvAPP
My XAML looks something like this
<RibbonGroup x:Name="PageRibbonGroup" Header="{x:Static p:Resources.Page_Ribbon_Group}" LargeImageSource="{svgc:SvgImage Source='pack://application:,,,/Resources/HomeTab/Page/page_group.svg'}">
<RibbonComboBox>
<RibbonGallery x:Name="PagesListComboboxGallery" SelectedItem="{Binding XPath=.}" MaxColumnCount="1">
<RibbonGalleryCategory x:Name="PagesListComboboxGalleryCategory" ItemsSource="{Binding}"/>
<RibbonGallery.ToolTip>
<ToolTip Placement="Bottom" Content="ASDF" ToolTipService.ShowDuration="5000"/>
</RibbonGallery.ToolTip>
</RibbonGallery>
</RibbonComboBox>
</RibbonGroup>
This happens from what I see on every tooltip that is on an Element that is in a dropdown.
I can't find a reason on why this is happening.
I've also created a repo https://github.com/SebiCiuca/RibbonToolTipFlicker
For combobox and dropdown button you can reproduce this behavior, but for Button3 the Tooltip works fine.

Looks like a WPF Bug, that should be fixed in future .NET6 releases.
This behavior does not reproduce in .NET5.
