cinnamon numix theme alt tab has no "selected" frame

Can't tell which window will get selected. Had the same issue on two machines (the other was ~1 year ago, and now)

Also, the icons were incredibly grainy/pixly/horrible as well, not sure if just on first boot after install or what that was about - but again, that happened both a year ago and now, though I have no screenshot of that.

This makes the theme unusable to me - I'd have to mentally count how many times I press tab and there could be a lot of windows..

Ideally I'd also want a small program icon in the corner for thumbnails, because different application can have similar appearance - though I suppose that's on cinnamon's end.

This makes for a bad early impression, and it's not obvious that it's the numix theme causing it.

Ah. #46 is the same thing. Apologies. I do bring a screenshot though :> (let me know If I should close and reply there instead)
