Brand Assets cannot be previewed. Only a small section of the top/left corner is visible.

I noticed the ASSETS area (found on the BRAND tab) now has an unusable and confusing "zoomed-up" version of the assets rather than the desirable and useful "full-version"  display.
If this is a user setting, what steps can I take to revert to the old (useful) option?
If this is a platform-wide change, how do I request this be improved?
