What's the problem? Describe what went wrong.
The marble's shadows are sometimes incorrect. Occasionally, the shadow is not positioned next to the ball; at other times, there are two shadows, one of which is in the wrong place. This does not happen on console (as far as I can tell, there is only supposed to be one shadow).
What steps will reproduce the problem?
Simply play the game and wait for weird shadows. It can also be seen on the demo that occurs after waiting on the title screen.
The nature of the glitchyness seems to vary based on the backend in use when recording. D3D11 and OpenGL glitch in slightly different ways (this may just be me picking up a patern out of random behavior though). All screenshots and logs were taken with D3D11. My computer is too old to use D3D12 or Vulkan with my GPU, but I was able to test D3D12 with "Microsoft Basic Render Driver" and it also happened there.
Is the issue present in the latest development version?
Tested in 5.0-11333.
Is the issue present in the latest stable version?
Yes, in 5.0.
If your issue is a graphical issue, please attach screenshots and record a three frame fifolog of the issue if possible.
Short 3-frame fifolog: MarbleSagaShadows2.dff
There is also a much longer 120-frame fifolog in MarbleSagaShadows.7z (some frames to look at: 13-15, 109-112). Note that for some reason the ball glass and crystal go invisible for parts of this when playing it back; that didn't happen when recording. When the glass is invisible, there is no shadow to look at.
