Summary	01809: Scanline Effect distortion on Vertical Orentation
Description	I've been using the scanline (scanlines.png) effect, but on games that use a vertical orientation (contra, xevious, digdug, ect) there is a visible line where the effect overlay does not line up properly. If the go into the Video Options and switch the aspect ratio from Standard (3:4) to the alternate setting, the problem goes away.
Steps To Reproduce	use Mame.ini defaults run with -effect scanlines

How much is it magified? Are you using -video ddraw or d3d? Are there other video related commands that might be interfering?

I took the picture with my digital camera. Video: Monitor 00010001 = "\\.\DISPLAY1" (primary) Direct3D: Using Direct3D 9 Direct3D: Configuring adapter #0 = NVIDIA GeForce 7650 GS Direct3D: Using dynamic textures Direct3D: YUV format = RGB Direct3D: Device created at 1440x900

No.00994 Yonah Tester May 16, 2008, 20:34	1400x900 is the native resolution of my LCD monitor and the aspect ratio should be 16:10. I have always left the setting in Mame.ini to Auto, and it seems to give the same results as using 16:10, so I would assume MAME is using the correct aspect. Here is what I tried running Digdug: AUTO or 16:10 = Standard (3:4) glitch / Pixel Aspect (7:9) OK 16:9 or 3:4 = Standard (3:4) OK / Pixel Aspect (7:9) OK What I find interesting is that the glitch disappears when the screen is rotated twice, so the screen is upside down. I checked some older versions just now. For me, this problem started with version 0.124. I just tried 0.123 using the same config I use now and the glitch does not appear.
