Font looks blurry after translate in Chrome

Question

EDIT 2016-07-04(Since this question is getting popular): This is a bug in Chrome. Developers are actively working on a fix.

EDIT 2017-05-14 The bug seems to be fixed, the fix will be introduced in Chrome 60

EDIT 2018-05-04 A fix has been merged, but the bug still appears to be present.

So I have this very ugly-looking window that is centered on the screen by this CSS:

.popup
{
   position: fixed;
   top: 0;
   bottom: 0;

   transform: translate(-50%, -50%);
}

However, it looks like this on Chrome (the font looks really blurry):

But like this on Firefox:

When I remove the transform rule, the text looks nice and crispy again, but then it's no longer correctly centered.

When I go to chrome://flags and execute #disable-direct-write it looks nicer, but users are obviously not going to do that and it doesn't solve the problem.

How can I make my font look nice while still having the window centered?

My chrome version is 44.0.2403.155

I have a three.js demo using WebGL that renders on a background canvas. When I disable the demo, the problem no longer occurs.

JSFiddle with the background.

JSFiddle without the background.

subpixel rendering..... can you have a defined width for `.popup`? — Daniel A. White, Aug 16 '15 at 11:33
@DanielA.White I could probably do that, but I prefer not to. You mean setting the width to `x` pixels and then do a `margin-left` of `-x` pixels? — joppiesaus, Aug 16 '15 at 11:36
I am using chrome version 45.0.2454.37, And it seems the problem is resolved, https://jsfiddle.net/5Lgsmjw9/ — Laxmikant Dange, Aug 16 '15 at 11:37
@LaxmikantDange Which means the problem will eventually solve itself? — joppiesaus, Aug 16 '15 at 11:41
@joppiesaus did you try to add `transform: translateZ(0)` (in your case it'd be `transform: translate3d(-50%, -50%, 0)`? — sergdenisov, Aug 16 '15 at 11:48
@joppiesaus could you add the working code snippet on http://jsfiddle.net or here? — sergdenisov, Aug 16 '15 at 12:01
@SergeyDenisov http://jsfiddle.net/xa0o9s6y/ This is odd. The problem doesn't seem to occur in this demo. — joppiesaus, Aug 16 '15 at 12:11
@SergeyDenisov I updated the problem, it's something with the background thinggie I'm making — joppiesaus, Aug 16 '15 at 12:16
@joppiesaus yes, it's OK in the JSFiddle in Chrome 44 on Windows 7/8.1/OS X. You should add your background in the JSFiddle. — sergdenisov, Aug 16 '15 at 12:19

A suggestion from a related discussion solved the issue for me: https://stackoverflow.com/a/46117022/7375996

Using calc with some offset solved the issue in my case:

transform: translate(calc(-50% + 0.5px), calc(-50% + 0.5px));

I've tried different solutions in different, sometimes scary, combinations:

translate3d instead of translateY
zoom:2; transform: scale(0.5); or zoom:0.5; transform: scale(2);
transform: translate(calc(-50% + 0.5px), calc(-50% + 0.5px));
-webkit-filter: blur(0);
perspective: 1000px
scale(1.0, 1.0)
-webkit-font-smoothing: subpixel-antialiased;

none of them work in july 2019.

The only solution i found for modals, that should be centered - to use a flexbox aligment instead of transform: translate.

.modal__container {
  display: flex;
  justify-content: center;
  align-items: center;
  position: fixed;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  background: rgba(0, 0, 0, 0.5);
}

  .modal {
    box-sizing: border-box;
    max-width: 80%;
    max-height: 80%;
    padding: 20px;
    overflow-y: auto;
    background: #fff;
  }

<div class="modal__container">
  <div class="modal">
    Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.
  </div>
</div>

flexbox it's ideal with one modal/popup, when you need multiple in different positions you are in trouble — chifliiiii, Dec 06 '19 at 14:30
Yes, every modal needs it's own container in situation with multiple modals on different positions. — Александр Михайлов, Dec 25 '19 at 16:31

Problem in half of pixel.

Try: transform: translate(-50%, -51%);

It will work!

No, it does not work. it might look nicer at a specific situation and specific resolution, but this is not a solution to the problem. – joppiesaus Aug 10 '16 at 16:15

Give me example when it's not working. This problem exist only in Chrome. I saw many solutions like `translateZ(0)` or `perspective:1000px` or `z-index:1`. Idea to move your layout to another layer. But problem in many cases when you are using `scale(1.1)` or `translateX(-50%)` not enough: 0.5px and browser making text like blurry. In many cases you can change height of current tag (Add 1px). – egor.xyz Aug 11 '16 at 20:33

I found out -webkit-filter: blur(0) could fix your blurry font in Chrome on Windows:

JSFiddle

#projectPopup {
    ...
    -webkit-filter: blur(0);
    -webkit-transform: translate(-50%, -50%);
    transform: translate(-50%, -50%);
}

@joppiesaus oh, it's strange(. It's OK in my Chrome 44 on Windows 7/8.1/10, OS X, Ubuntu 14.04, something like [this](http://oi60.tinypic.com/jpy8sx.jpg). Which OS do you use? Is [this snippet](http://jsfiddle.net/sergdenisov/8vfz9m29/2/) crashed too? – sergdenisov Aug 19 '15 at 16:28
It's probably because I'm using Chrome 45 now. I'll test it on Linux with the latest stable version(44), I'm sure that will be fine. – joppiesaus Aug 20 '15 at 10:07

Use a normalization of the transform after your animation:

Transform X/Y normalization

Or We scale the texture with zoom double, then scale down again. In some cases this cannot be applied due to other complex transformations or translations, and is not perfect.

...{
zoom:2;
-webkit-transform: scale(0.5);
transform: scale(0.5);
}

`scale` and `translate` do not really mix. This ended up moving my text down too much. – trysis Mar 08 '17 at 20:32

2019-04-15, still happening to me in Chrome. Found that changing position: fixed to absolute fixed it:

.popup
{
   position: absolute;  <-- just like that
   top: 50%;
   left: 50%;

   transform: translate(-50%, -50%);
}

Using absolute may or may not suit your particular case, just my 2 cents.

The only solution that worked for me:

Translates can cause blur due to result not being rounded to the nearest pixels, so rounding the div height to an even number fixes it.

We can't do it in CSS as it doesn't know yet its final height, so we have to do it after rendering. Using Jquery is a breeze:

$(window).on("load", function() {
    if($('.popup').height()%2==1) $('.popup').height( 2*Math.round($('.popup').height()/2 ) ) ;
    if($('.popup').width()%2==1) $('.popup').width( 2*Math.round($('.popup').width()/2 ) ) ;
});
