Summary 100vw by 100vh filter not being updated on window resize

Created attachment 465423 [details] Filter not fullscreen after making windowheight larger When applying a filter to a fullscreen html element (100vw by 100vh), the filter will not resize on window resize. The element will be full width and height, but the filter still shows up on the old resolution. After a refresh the filter works on that resolution again, but going to a bigger screen / higher resolution will break the filter again. Issue can be recreated with code in attachment. In codepen slide up the bar between the code and the content. Or on a webpage go into developer tools -> make the windowheight smaller -> refresh browser -> make screenheight bigger again.

Thank you for the report! This screenshot looks like Chrome, does it affect WebKit? Also, could you please attach the source of the test case or provide a link, so that we wouldn't have to retype it?

I wasn't sure if i could post links here but here you go: The issue first appeared on my personal website (https://www.mennoveerkamp.com). To make it easier to troubleshoot i reproduced the issue on codepen(https://codepen.io/MennoVK/pen/poOaMRe). I have tested this issue in Chrome, edge, Opera and Firefox. The issue happens in all those browsers EXCEPT Firefox.

Adding a filter: blur(0) on the element that has the backdrop filter will fix the issue.
