I reported this on the bug page but might as well cross-post here.

On my site, www.witf.org, images often get squashed in crazy ways. There is no method to its madness, it happens in the top images, sidebars, modules, etc.

It doesn't happen every time, and when it does a refresh usually solves it. This is embarrassing as images get insanely distorted. I can't figure out what's causing the glitch.

I've attached an image showing an example.

it's happening in all browsers on PC and Mac OSs. It doesn't always happen, so if you go to the site you very well might not see it. If you keep visiting though you will.

Anyone seen this before? Any fixes available?

Thanks,

Chris
