Problems Detected
Work around a bug in offscreen buffers on NVIDIA GPUs on Macs: 89557
Applied Workarounds: needs_offscreen_buffer_workaround
Multisampling is buggy on OSX when multiple monitors are connected: 237931
Applied Workarounds: disable_multimonitor_multisampling
Multisampled renderbuffer allocation must be validated on some Macs: 290391
Applied Workarounds: validate_multisample_buffer_allocation
Unfold short circuit on Mac OS X: 307751
Applied Workarounds: unfold_short_circuit_as_ternary_operation
Mac drivers handle varyings without static use incorrectly: 322760
Applied Workarounds: init_varyings_without_static_use
Always rewrite vec/mat constructors to be consistent: 398694
Applied Workarounds: scalarize_vec_and_mat_constructor_args
Mac drivers handle struct scopes incorrectly: 403957
Applied Workarounds: regenerate_struct_names
glBindFramebuffer sometimes requires a glBegin/End to take effect: 435786
Applied Workarounds: gl_begin_gl_end_on_fbo_change_to_backbuffer
NVIDIA fails glReadPixels from incomplete cube map texture: 518889
Applied Workarounds: force_cube_complete
Accelerated rasterization has been disabled, either via about:flags or
command line.
Disabled Features: rasterization
