FW: Lyx 2.4 - strange rendering problem in Windows

[Dr Paul Verschueren]

Thanks to all for making 2.4 a reality😊.

I’ve just installed on Win11 and have a strange issue: when a document is scrolled or moved up or down, a ghost image is left behind (see screenshot below).
This disappears on single clicking in the document.
Has anyone else seen this behaviour, or is it just my system? Does anyone have any recommendations on things I should try before reporting it as a problem?
(I suspect a QT issue, but don’t know much about QT).
Many thanks for any input!
