I am trying TMVAMultiClass on my laptop with ROOT 6.17/01. Training goes fine, and when I attempt to use TMVAMultiClassGui for the usual graphical stuff, I notice something weird with the canvases drawn for the classifier output distributions (buttons 4a, 4b only. Others are fine).
When the canvas is first drawn, it looks fine

But, when I attempt to do any mouse manipulation with the canvas, like resizing the canvas, or even clicking on it, a bunch of components on it disappear

I don’t see such issues reported elsewhere on the forum. Is it possible that it is a peculiarity with my ROOT build? ( I should mention that I see the same issue with ROOT 6.16.00 on my university cluster)
I am unsure of how to provide a “test script” for this problem. The “TMVA.root” file generated by the training is 118 MB in size, so I doubt I can attach it to this post. If any of the experts reading this have access to CERN lxplus, I have stored the relevant file at /afs/cern.ch/user/a/avenkate/public/forTMVA/TMVA_Multiclass.root
I would be happy to provide any additional info from my side.
