We have a Rhino.UI.Controls.ViewportControl hosted inside a (modeless) Eto window. When Rhino 8 loses/regains focus (e.g. after being minimized or using another Windows application), an unwanted floating viewport appears. This happens in Rhino 8 only. I haven’t tried older SRs to identify when it started, but I noticed it only recently, which suggests it may have been caused by a relatively recent SR(C)? (It’s also possible it simply escaped my attention until now.)
Currently testing 8.9.24190.17001.
