Does this also happen with Vulkan?
If VulKan doesn't help, D3D on Windows 7 is missing some features that Dolphin uses, so I'd say try installing Windows 10 and getting Intel's latest drivers. If you don't want to mess up your install with windows 10, you can try partitioning your hard drive and installing Windows 10 there.
