To check if this is the culprit one may add the following line to your

\force_paint_single_char false
On a Mac this is the file "~/Library/Application
Support/LyX-2.0/preferences".
(Broken cursor placement for long lines should be one consequence.)
Will try this when I have some time.
I did not see significant changes with or without this line.
Out of curiosity: Can you try the same with "\use_pixmap_cache false" ?

Hi,
I think I should refine my previous statement. I mean that we are
entering into the "subjective" changes:
When I drag the scrollbar down on the "introduction" manual
- 2.0.1 is full scrooling smoothly (*), both in the text scrolling and
the toolbar scrolling.
- 2.0.2 "pristine" jumps in 2 to 3 steps (text and scrollbar): top of
the document, sometimes an intermediate step, and bottom of the document.
* Adding "\use_pixmap_cache" and setting to false or true has no effect
* Adding " \force_paint_single_char", set to false has a slight effect,
like there are now 5-6 steps and there are sometimes 1-2 areas where it
scrolls smoothly on a few lines. So I'd say subjectively this setting
removes 10%-20% of the regression.
Note that the issue is still present if scrolling up back to the top
then down again (IOW it's not a 1 time effect)
For the sake of completness, I have to say I now notice LyX taking 50%
CPU in all versions while scrolling fast, with I did not remember seeing
with 2.0.1 before (perhaps I was using another document and I was
scrolling on smaller areas ...).
Best regards,
Olivier
(*) If you look closely, the scrollbar sometimes may jump a 2-pixel step
with 2.0.1, but you really don't perceive that as a "jump". The 2.0.2
jumps can be like a 1 second freeze of the scroolbar and text (the mouse
cursor moving smoothly), then jumps several hundreds pixels down.
