Missing some lines in OpenGL rendering

[Lurka]

Hello,
OpenGL 4.4 on Intel Graphics 520 with driver ver. 21.20.16.4860
I noticed this problem when using OpenGL in build 6352, 6354 and 5934 (Direct3d is ok).

Some "thin" lines are not drawn, for example:
-in Tiger Woods PGA Tour 06 (Gamecube) there is no terrain slope grid on the putting green
-in Puzzle Quest (Wii) there are no path lines between locations on the map




In another build (don't remember exactly which one), Okami's divine brush overlay appears completely opaque, covering the scene behind.
They seem to be OpenGL driver bugs, rather than Dolphin bugs. Can you confirm? Any solution, other than using D3D?


Bye,
Lurka

The Intel windows opengl driver is notoriously bad. Seeing issues with that is not surprising.

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.
