In order to try and rule out the criterion as the main cause of the issue, I tried replacing the `MSECriterion` with both the `AbsCriterion`, and the `SmoothL1Criterion` criterions, which...

@htoyryla I think I made a breakthrough! New install with Cuda 9.0, and cuDNN v7: ``` Capturing style target 1 Running optimization with ADAM Iteration 1 / 2500 Content 1...

So I made it to an image size of 2816, where this new error occurred: ``` conv1_1: 64 3 3 3 conv1_2: 64 64 3 3 conv2_1: 128 64 3...

@htoyryla Here are my results from using your [neural-mean2.lua](https://gist.github.com/htoyryla/fdcab165b397b1b5c4986f4877454d3a):  Full sized comparison image link: https://i.imgur.com/2y5CnrH.jpg Full album link with style & content images: https://imgur.com/a/dUdzD It almost seems to act...

I've had a suspicion that [clipping](https://en.wikipedia.org/wiki/Clipping_(photography)), might be responsible for the grey spots/haze, but I haven't really had the chance to test the theory. It also occurs to me that...

@htoyryla This style image seems to cause grey spots/regions on multiple content images: Style Image: https://i.imgur.com/JZxUhfA.jpg Content Image: https://i.imgur.com/HKF5yGD.jpg The Output: https://i.imgur.com/dOYNv2e.png This is probably the best example for experimenting...

> My first assumption was indeed, that the grey areas result from something in the images which leads to weak activations in the feature maps. So maybe this can happen...

I have run into the same size limitation error [as before](https://github.com/jcjohnson/neural-style/issues/428#issuecomment-339228366), but this time with a higher image size of `3328`: ``` Capturing style target 1 Running optimization with ADAM...
