Images viewing squashed like a concertina

[RobinHammy77]

I'm getting a very odd issue with a work that I'm designing in CC2017. When I click into the images they haven't been squashed horizontally, and they immediately show perfectly. Has anyone seen this before? I've trashed the Prefs. But its still not correct.

Thanks

I'd bet you are using the GPU feature (it's turned on in GPU preferences, click the "rocket" icon on the Application Bar). It's probably a GPU bug. You can choose View > Preview on CPU.

Thanks Steve. Will try this and see how I get on. I seem to get a lot of issues with the GPU features in photoshop too. Wonder why its so glitchy.
