| Summary | 0000115: madvr v0.86.9 + xySubFilter beta: opaque black box on older GPUs | ||||
| Description | When using xySubFilter with an older GPU, a black box is rendered around subtitles on default settings. However, disabling the "optimize subtitle quality for performance instead of quality" option in the "trade quality for performance" section makes the opaque box go away. | ||||
| Steps To Reproduce | - set xysubfilter RGB output to AUTO - tick the "optimize subtitle quality for performance instead of quality" option -> the subtitles now have an opaque black box on older (nVidia 200 series) GPUs - untick the "optimize subtitle quality for performance instead of quality" option -> the opaque box goes away, subtitles are blended correctly | ||||
| Additional Information | Previously, setting image buffer to 10Bit while RGB output was set to AUTO also helped. Another alternative is setting RGB output to "PC" without having to set image buffer to 10Bit. | ||||

You might need to restart the player after toggling the option. Going from "performance -> quality rendering" works without restart, going "quality -> performance rendering" needs a restart to make the opaque box reappear. Also, the option name is a bit confusing to read, how about "optimize subtitle rendering for performance instead of quality"? |

I've found the older GPUs (at least my NVidia 9400) can do alpha blending just fine with 10bit integer, 16bit floating and 32bit floating point textures. The only format they have problems with is 16bit integer - and that's the format usually used by madVR internally. All those options you mentioned which fix the problem happen to result in madVR choosing a different texture format (some other than 16bit integer) for some reason or another. The next build will automatically select a texture format which supports alpha blending. This should fix the problem for all GPUs which can do alpha blending with *any* of the mentioned texture formats. I will not go back to 8bit texture formats, though. So if a GPU only supports alpha blending with 8bit textures, then all hope is lost for that GPU. |

Somehow this issue still happens to one particular ASS file with any video file... With forced 10-bit buffer mode, it works fine again. |

Can't reproduce this problem with my NVidia 9400. Are you sure you've been using v0.86.10? If so, please upload a debug log, maybe it will help identifying the problem. It's very weird that you have this problem only with one specific ASS file, in any case. All other ASS files work alright? |

Same as madshi, can't reproduce on my 260GTX neither in software nor DXVA mode. |

Oh.. I am sorry about the misleading! It does happen to other files. @_@ I was verifying the contents on another system first w/o any issue. On this ION system, I didn't identify this issue with too many combinations last night. Now I can confirm the issue ONLY seems to happen if I use the old "settings.bin" from the previous version. Remove it and the issue is gone on this system. Sorry again about wasting your precious time! |

Interesting. Not sure why the old "settings.bin" would have that effect. But since it seems to be a weird and rare case, I'll simply close this issue again. |
