Poor performance with Eto's text elements

Hello,

We’ve recently been migrating our UI from WPF to Eto.Forms but have noticed that Eto’s TextArea (with SpellCheck disabled), TextBox and Label can cause Rhino to hang for significant periods of time when the parent panel is dragged or resized if there’s lots of text (~10,000 lines +). The issue seems to persist regardless of which layout the text is in (tried both DynamicLayout and TableLayout).

When I pause the debugger while it’s hanging, the call stack on the main thread looks like this:

WFP’s TextBox is able to handle the same amount of text without issue, so I was wondering if there are any remedies.

Thanks
