Summary0000155: When a video height is non-mod4, madVR will add padding on bottom of the frame when taking screenshots
DescriptionI found that when making a screenshot (using the screenshot fucntion of MPC-HC, not grabbing with printscreen) of a video that has merely mod2 height, MadVR seems to add black padding at the bottom. For example, with video that is 720x478, two black lines will get added at the bottom, example: http://i.imgur.com/xzGWBes.png [^]

Mod4 height resolutions seem unaffected.

I tried to make a shot with haali/VMR7w instead and those seem to work fine, so it should not be a bug in MPC-HC (at least I think).
I'm not sure when this got broken, because I only update from time to time, however screenshotting stuff with 478 height definitely worked fine in older versions of MadVR - f.e. version 0.84.2 is unaffected by this.



Here is a sample (4,3 MB, few seconds) video that triggers it for me (I hope it helps...): http://ulozto.net/xwvrz4Kw/andromedastories-sample-madvr-screenshot-padding-error-mkv [^]

(copy attached)
Steps To ReproduceDuring playback of video with a non-mod4 height (probably, I encountered this with mod-2 height), use the video player screenshot tool (for example in MPC) to capture a screenshot from madvr.
Additional InformationI use the iGPU in AMD A8-3850 (Llano, Radeon HD 6550D with WLIV5 architecture) with latest drivers from windows update: 13.251-131206a-166151E-ATI
madVR version: v0.87.4. This is on Windows 8.1 64 bit. OpenCL dither is disabled, chroma upscaling is set to lanczos3 AR (jinc3 AR for luma). I don't use deinterlacing, debanding, smooth motion or other postprocessing. I also only use windowed mode, not exclusive FS.

It seems that version 0.86.9 is also unaffected.
