Resizing edges of window causes chart to disappear

hello, apart from the anti-aliasing issues caused by SU5 and the missing pink a/c marker for moving maps, I’m now having a problem (in VR) whereby when I try and resize the app window the chart disappears…this works in fit screen mode and the standard layout.

perhaps this is also a culprit of SU5?

I am using a Reverb G2, 2080Ti and 9700K and the hotfixed SU5 that was released earlier today.
