Rendering from or to integer texture is buggy in chrome |
||||||||||
Issue descriptionSome known scenarios this bug would happen: (1). If base level of an integer source texture > 0, result of drawing from source texture is wrong. I see this on Windows at least. (2). If base level of an RGBA formated texture > 0, result of drawing from source texture to a fbo attacing an integer dest texture is wrong. I see this on Mac OSX at least. This blocks gl_tests for CopyTextureCHROMIUM when level > 0. I am going to add conformance test to track this bug.

Thanks for tracking this down Qiankun. If it's not possible to work around these bugs then let's temporarily disable the gl_tests for them, file Radars, etc.
