I've been using MetaPDF for annotating some PDF documents that I sync to my Google Drive. It works reasonably well in Firefox, but in Chromium sometimes it seems that the app is using a lot more resources than I would expect (especially CPU), and it eventually freezes after adding a couple of annotations.
Do you support Chromium? If so, are there any known performance issues?
I use Chromium for all my internet browsing, so it's a hassle to (remember to) switch to Firefox whenever I need to annotate a PDF.
I'm running Chromium 57.0.2987.98 running on Ubuntu 16.04 (64-bit).
