Steps how to reproduce with SeaMonkey en-US 2.39a1 Mozilla/5.0 (Windows NT 6.1; WOW64; rv:42.0 from official download area)  Gecko/20100101  Firefox/42.0  Build 20150801224600  (Classic Theme) on German WIN7 64bit:

Simply use browser for hours and often use mouse wheel for quick scrolling down. Few times per hour you should see gaps in the page view as shown in the attached screenshot.

Similar gaps also appear in drop down box lists (but that might be a separate bug?):

1. Log in and open advanced Bugzilla search
2. Most left selector in "Custom Search": Click into selector and
   use mouse wheel to scroll down 1 jump as fast as you can.
   » if problem appears you will see few lines gap in the list what
     will be closed after few seconds.

Additional information:
a) I am very sure that I did not see that problem until 2.33
b) I am pretty sure that I did not see that problem with 2.35
c) I used 2.36 and 2.37 too few time to reproduce the problem, but
   currently I use 2.39 all day, so that I see these gaps several 
   times per day

I should have mentioned:
d) Different to observations in my step 2 in drop down lists the gaps
   in web page view will not be closed automatically
Status: NEW → UNCONFIRMED
Ever confirmed: false

e) As expected also (only html?) Mail view is affected
Perhaps we've inherited Bug 1187619 - Graphics corruption when scrolling, & if so, maybe we'll inherit a fix :-).

Yes, that one looks very similar. My observations differ in some details, for example in  Attachment 8639783 [details] I see a white table background in the gap, not a blue one. But those differences might be caused by some smaller differences in the test conditions. 

I will do some more tests and probably mar this one as a DUP.

Can you still reproduce the issue with latest pre-alpha?
