Menu: Scaling causes menu items to disappear when placed in a dropdown in the Windows11 theme

Hi,

We have noticed another issue with the Toolbar when using Windows 11 Theme.

If we have a toolbar with 3 items, as below:

This looks fine. But if we change the scale settings in windows to be 125%, then we see the following:

This persists even if you have rebooted since changing the scale.

I so not see this with a different theme.

Sample attached.

Please note that this is using the internal 2022.3.1128 hotfix build, which does fix the issue that we were previously seeing with the item layout. It is also present in 2022.3.912.

Thanks

Carl

Hi Carl,

I'm glad to hear that the proposed workaround resolved the issue for you. I do hope you find it suitable for the time being while we manage to come up with a viable fix.

Hi Carl,

Thank you very much for the provided project and images.

I can confirm that I was able to replicate the undesired behavior at my end. I have thus converted this thread to a bug report. I've also awarded you with some Telerik points for bringing this to our attention.

I just want to clarify that this issue does not require the RadToolBar and can also be replicated when using only a RadDropDownButton.

For the time being, as a workaround, I can suggest using a VirtualizingStackPanel as the ItemsPanel of the menu:

                    <telerik:RadMenu.ItemsPanel>
                        <ItemsPanelTemplate>
                            <VirtualizingStackPanel />
                        </ItemsPanelTemplate>
                    </telerik:RadMenu.ItemsPanel>

Please let me know if doing so would work for you and whether this resolves the issue in your original application.
