Weird artifacts with d3d11 #5353
Comments
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. |
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 |
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. |
This should be fixed in SPIRV-Cross git master. |
Thank you @rossy for taking care of this.Much appreciated. |
