I think you are using jetpack proton plugin.
Please try to disable it to see if it fixes your issue.
I taken another look using another computer of mine, A Lenovo Horizon running Windows 8 and IE 11, I did not see the “shrinking frog”.
If disabling jetpack plugin does not work for you, I suggest you disable one plugin at a time to eliminate any conflicting plugin.
You can also try disabling any browser addons.
