Hi! I have issue with TextField label if variant="filled" is set then label will become blurry on focus or unfocus.

• The issue is present in the latest release.
• I have searched the issues of this repository and believe that this is not a duplicate.

Current Behavior 😯

Click to edit field and you will see blurry label for about 1 second like this

Then it will return to correct crisp view

If variant="filled" not set label always crisp.

Expected Behavior 🤔

Label should be always stay crisp (not blurry).

Context 🔦

It seems that this is old CSS Translate issue in Chrome browsers with hardware acceleration turns on.
I don't have such issue in Firefox for example.
Also interesting fact that Google doesn't have this issue in their signup page.

Please help! Thank you!
