User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:68.0) Gecko/20100101 Firefox/68.0
Steps to reproduce:
- clean profile (can be reproduced in stable and nightly)
- open https://elinux.org/images/d/d3/Z3fold.pdf
- press few times (5?) on Page Down waiting for decode in between
Actual results:
Memory usage can easily go above 2GB when decoding on load and after paging. Seems to be released after some delay/unspecified event.
Expected results:
Memory usage should not increase a lot when decoding.
PDF decodes without memory problems in Chromium 73, Okular 1.6.3.
Looks similar to this: https://bugzilla.mozilla.org/show_bug.cgi?id=1436734
but easier to reproduce and capture memory report.
