|Summary||07587: Artwork: multi-screen layer blending problem with BGFX|
Artwork: layer blending problem with BGFX.
This is a bug specifically witnessed with hydef's Game&Watch artwork, and only for the dual-screen games. It could be related to https://mametesters.org/view.php?id=7586 , however it does not only apply to D3D9, but all BGFX backends.
|Steps To Reproduce||
- install hydef's G&W artwork (his google drive: https://drive.google.com/drive/folders/1WLKcvynl0ky2mRL1UacA9yaiMTnNs4x5 )
- mame64.exe gnw_zelda -video bgfx
or any dual-screen G&W
Look carefully at the 1st screen (left screen for horizontal, upper screen for vertical).
hydef applied a layer effect to simulate LCD screen shadow. It is missing on the 1st screen.
|Additional Information||MooglyGuy was already informed of this bug a while ago, he verified it and suspected it is something with screen chains.|

mame64.exe nummunch -video bgfx -bgfx_backend d3d9
in 'cocktail' view, the bottom screen is visible however:
