Emulator

Yes, please confirm that changing Internal Resolution to "Auto (Fractional)" will fix this problem.

Same issue occurs with Internal Resolution on "Auto (Fractional)".

Same issue also occurs with OpenGL and DirectX 11 plug-ins.

Do you have OpenCL enabled or disabled?

Enabled, but problem persists with it disabled.

For this testing, would you please disable OpenCL? If you change the Internal Resolution to Native, the gaps are closed, correct?

Does EFB Scaled Copy have an effect on the problem?

What about AA?

OpenCL disabled for further testing.

Gaps are not closed with Internal Resolution to Native either.

EFB Scaled copy and AA on/off doesn't seem to make a difference. Sorry to have spammed the initial post with irreverent settings.

Sorry, one last question: The lines are not present on the real hardware, right? Maybe start trying old revisions of Dolphin to check when this issue started occurring.

No, they are not, see http://www.youtube.com/watch?v=DK1yIJvZzs8.

It seems to me that the polygons aren't moving together properly. In motion you can see the gaps close & open to varying pixel gaps (say 1-3 pixels) as you travel vertically. Also, there seems to be something else going on. There's something showing up above the tank layer as seen in this screen shot.

I noticed that the OpenGL plugin with Real XFB enabled closes the gaps.

Also confirmed with Direct X 9 plug-in, though such significantly reduces graphics quality.

Native mipmaps on/off makes no difference, at least in DirectX 9.

Yeah, you are right. It was a bit random and i jumped to conclusions...
