Marching ants selection animation uses 26% of GPU even while minimized

[Zoot 17]

I noticed (still on build 209 here) that if I have a rectangular selection resulting in the "marching ants" selection border animation, that my GPU utilization (Intel integrated graphics) according to Task Manager sits at 26%, even with Photo minimized.

This seems excessive for something I can't even see

Hey Zoot,

We've known about performance hits with marching ants for the get-go. A common issue we see is users complaining they are getting poor performance on their files and this is often caused by a tiny/hidden pixel selection.

There isn't much I can suggest at the moment I'm afraid

This isn't a performance problem, the issue is that the marching ants are animated, so we have to constantly render to the screen (normally we only render when a change occurs). We should look at pausing the rendering when the application is minimised, as that does seem excessive. Also, marching ants across multiple documents in the same tab group will no longer affect performance (since a few betas ago).
