Same here when using ewa_lanczos with d3d11,after awhile start having black screen with sound only(.mkv file).Uploading log file as well for better troubleshooting.
P.S. No problems with spline36 also same GPU driver as OP

Strange. I do observe these artifacts (though not as serious as you observed) with shinchiro's build (20180104). But when I was trying my own build, artifacts were gone.

This my guess. Probably this is another spirv-cross bug yet? Too bad mpv doesn't print spirv-cross git version

[zc62]

I was using google/shaderc@98ab88b and rossy/crossc@ad956db, which pulls KhronosGroup/SPIRV-Cross@bcc96d8

I get this as well. It seems to be a change in how barriers are emitted by glslang, which is exposing SPIRV-Cross's limited support for SPIR-V barriers. Working on a fix now.

[rossy]

This should be fixed in SPIRV-Cross git master.

Thank you @rossy for taking care of this.Much appreciated.
