[PuraIgnis]

Important Information

Provide following Information:

• mpv version ( latest version by shinchiro )
• Windows Version ( Windows 10 )
• Source of the mpv binary - ( https://sourceforge.net/projects/mpv-player-windows/files/64bit-v3/ )
• If known which version of mpv introduced the problem - ( I am using the latest version )
• GPU model, driver and version - ( AMD Ryzen 4800H with Radeon Graphics. Driver version: 31.0.21912.14 )
• Possible screenshot or video of visual glitches
  

Reproduction steps

It happens when I use --gpu-api=vulkan. Changing it to d3d11 would eliminate the issue.

Expected behavior

Video plays.

Actual behavior

Flashing screen, but audio is still there.

@haasn: Do you think we can optimize this memory allocation to work also on Vulkan?

Also I notice error handling is not great

[   2.715][e][vo/gpu-next/libplacebo] input:67: error: '' :  syntax error, unexpected LEFT_BRACE, expecting SEMICOLON

probably some NULL is substituted in shader code.
