I am suffering from this bug too. While scrolling, Xorgs cpu usage increases (moderatly), while the process lyx uses 100% CPU. Scrolling too far causes the window to grey out, typing text becomes impossibly complicated due to the lag. None of the proposed fixes above changes anything for me ...
@lyx-devs, is there anything I can do to provide tests that can help? This is breaking lyx usability for me, and it's not a piece of software I'd like to sacrifice with a shrug.

This program used to be my do- everything software, but it has become unusably slow. That is, keystrokes are even delayed in displaying when I type. The rest of the system is fine, and LyX didn't used to have such a problem.
