There is now a 15.45.14.4590 available:
https://downloadcenter.intel.com/download/26563/Graphics-Intel-Graphics-Driver-for-Windows-15-45-
And a Beta 15.45.4614

There is probably nothing we can do about it. If you get the same problems
with Firefox 49 this would point to either a bug in Gecko or a problem with
your OS and / or configuration.
The Intel adapters use system memory to store graphics data.
Try memtest and check if your memory has problems:
http://www.memtest.org/
Also if you you PC uses only one ram slot and has two buy a second one with
identical specs. With previous Intel graphics adapters screen corruption did
occur when they were not running in dual channel mode. On my company laptop I
see white streaks and occasional rendering failures too under Windows 7.
Memtest should report how your system is configured.
You could try Adrians 2.48 and see if this is fixed in a later version:

The official 2.48 or 2.49 whatever comes earlier can be installed over it with
no data loss. Please backup you profile if you want to go back to 2.46.
Instead of Windows 10 I would also recommend 8.1 with classic shell. With the
half baked changes Microsoft is doing right now and the spotty Intel driver
support this won't get any better in the long run.

I previously asked a similar question about tab content only, but the problem
now affects more than that.
This began after I installed 2.46 (previously using 2.42). Two or three times
a week, I will load a page that doesn't completely render and still shows
parts of the page (in another tab on the same window) I just left.
Waiting a few seconds to a minute often let's it clear on it's own; paging
down/up almost always renders it correctly; closing the window and trying
again often renders the pages correctly.
Rebooting fixes it for a couple days, at least.
It's getting worse: now, a new window - no tabs, no website - can have
incomplete rendering: a black bar directly under the Bookmarks toolbar. If I
hover the cursor along the black bar, it renders that portion of the bar
properly. Tab pages still do not render correctly, however.
It even affects a "Search messages" window, with incomplete rendering along
the top.
It has the Intel HD Graphics 530 Driver version 20.19.15.4549 driver (Nov 25,
2016 for the win 10 anniversary update) installed, which is supposed to be the
newest version. Hardware acceleration doesn't seem to be an option with my
computer. Hardware acceleration is not selected in SM.
I ran the Win 10 Troubleshooter, which said it fixed a problem, please
reboot, so I did. After a day or so, the improper rendering returned.
The responses to my previous question were about the video driver, and I
detail that above. To test if it is SM 2.46 that is causing the problem,
perhaps I should revert to 2.42 (not sure how to do that)?
