:mattwoodrow,

Your atch seems to cause the regression. Can you look this?

Recent regression, tracking with the hopes that we'll investigate and potentially fix this soon.

Too late to fix in 57, but we could still take a patch for 58.

Not sure if this is still reproducible. I'm seeing big white text over a background image. 
Are you still seeing the bug?

Comment 6

[frederik.voordeckers]

I added a workaround myself. found out that the combination with 'preserve3d' will mess with the rendering.

Comment 7

[frederik.voordeckers]

But the bug is still there

So, It means that the problem is not reproduced with the URL specified by comment#0, OK?

Could you provide testcase or public url to reproduce the issue?

Comment 9

[frederik.voordeckers]

The problem cannot be reproduced on that url. 
I cannot provide another test case atm. 

The only thing I know is that it doesn't work to change the css, the issue occurs during rendering time. Modifying the css after it loaded will not let you reproduce the issue.
