this error means The GPU is freezen
Phyre::PSemaphoreOrbis::wait()//callstack
something illegal in command buffer submitted
the system is waiting the render thread to complete
so you need to check out the render command
including the textures and targets
comment out some of these rendering commands until freeze stops\
我这次遇到的似乎是 targets不对导致的 因为我重置了 yebis的effect source depth source && destination source
seems about msaa type
Game shader or System shader is busy ::VS CSG
