This is a P3 non-blocker if it's an out-of-date driver with available updates. This works on OSX+NV for me. (GT 750M)
Hi Amy, Since I saw you add some hosts which also includes t-yosemite-r7-0340 in Bug 1269769, you might know about some driver information. Could you please offer what gfx card version in this machine we used for running try? It can help to verify the issue. Thanks.
We have the late 2014 model, so per https://en.wikipedia.org/wiki/Mac_Mini#Specifications it's the Intel Iris Graphics 5100. System_profiler says: Intel Iris: Chipset Model: Intel Iris Type: GPU Bus: Built-In VRAM (Dynamic, Max): 1536 MB Vendor: Intel (0x8086) Device ID: 0x0a2e Revision ID: 0x0009 Displays: Display: Resolution: 1600 x 1200 @ 60 Hz Pixel Depth: 32-Bit Color (ARGB8888) Display Serial Number: 1600x1200 60 Main Display: Yes Mirror: Off Online: Yes Rotation: Supported
There is actually an ANGLE workaround flag for the compiler for this, so we just need to figure out where this is needed. Since this shouldn't hurt perf, we can just target all intel+osx.
