@holzgeist Sorry it's taken me a bit to get to taking a look at this! Would you be able to add some context to the pull request description outlining the issue this code fixes? Is it by chance related to #8 / #9 ?

That being said, I tried it out your changes locally in the example app and it doesn't seem to break any of the existing behavior. Reading the code though my guess is that the example app may not exercise the edge cases, so before merging something like this I want to make sure those scenarios are properly captured to protect against any potential regressions.

Thanks for looking at it. Not it's my time to apologize for the long pause!

The problem only occurs on mobile browsers, when the phone is rotated while blurring is on

Start:

after rotation without fix
