This is a lot like bug 1304360, except for the Intel GMA 3600 in an Atom-based netbook my parents have. The Device ID (0x0be1) doesn't appear in the list of devices in widget/GfxDriverInfo.cpp, so I'm not sure if attachment 8794983 [details] [diff] [review] will help.

1, Use Firefox 49.0.1 on a HP XX netbook
2, Open
3, Scroll down and see artifacts (see attachment)

Reverting to 48.0.2 solves the problem, so does disabling hardware acceleration in the advanced preferences.
Attached file about:support
gw280, could you confirm this is similar case of a buggy D3D9 fallback ?  Unfortunately I won't have access to this machine very soon, so won't be able to verify any settings or run test builds from bug 1306689.

Nick, when you do get a hold of this machine, could you check if setting layers.allow-d3d9-fallback in about:support to false (and restarting) make the problem go away?

Version: Trunk → 49 Branch

Assuming this affects the versions between 49 and 52 as well
platform-rel: --- → ?
Whiteboard: [gfx-noted] → [gfx-noted][platform-rel-Intel]
I've asked my parents to try flipping that pref.
Flags: needinfo?(nthomas)
They've confirmed that flipping layers.allow-d3d9-fallback to false works (with 'Use hardware acceleration when available' ticked).
Flags: needinfo?(nthomas)
That would suggest the patch in bug 1306465 should take care of this.

Sorry, should have just made the tracking flags match rather than removing the regression keyword.
