User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:45.0) Gecko/20100101 Firefox/45.0 Build ID: 20160413010702 Steps to reproduce: 1. Go to https://web.whatsapp.com 2. Some panes are not rendered (see screenshot) 3. Disable the transform: translateZ(0) property in web inspector: panes are now rendered correctly 4. Enable it back: some panes are not rendered anymore Actual results: Without the transform enabled, rendering is OK. With the transform enabled, some panes are not rendered. They can be rendered at a later point depending on the activity on the page. For example, popping up a menu (the one from whatsapp) makes the pane render correctly. Expected results: Pane should be rendered consistently. Debian Linux unstable. Firefox 45.0.2 from Debian unstable.

After upgrading to Firefox 46, the problem doesn't appear anymore. Should I close with WORKSFORME or INVALID?
Debian did release a new version of Firefox using GTK2 instead of GTK3 (due to an unrelated bug). The present bug appears again. So, it seems to be linked to the use of GTK2. Dunno if it's worth investigating.
Severity: normal → S3
