Build ID: 20180327223059
Steps to reproduce:
Use a CSS filter on an image (any filter). The bug is more noticeable when the filter is applied through JS, otherwise the long time it takes to apply the filter blends with the time of loading the page.
Actual results:
The filter is properly applied, but it's way too slow
Expected results:
The filter should take effect much more faster. Compared with desktop Firefox, desktop Chrome, android Chrome, generic android browser; Filters take effect much more faster in all of them

Please provide a specific self-contained test case and define what "too slow" means as the term is very subjective. Thanks.

Sorry about the delay. Here is a minimal test case:
https://gist.github.com/alx741/a8a81de51f09cdf7f70c4ddc56cdbc0a
The script applies a filter (grayscale, but the issue occurs for every filter) to the image when it's clicked/taped.
On Firefox, Chrome, Chromium and Android chrome the results are as expected: as soon as the image is clicked, the filter gets applied immediately.
On Android Firefox only: when the image is clicked it takes about 10 seconds before the filter takes place
