While scrolling in Gmail interface with new composer is opened I've started seeing some graphical weirdness in header of email conversations. See in screenshot attached (zone is marked with red ellipse).

But NVIDIA..., most likely is Bug 782311.

(In reply to Alice0775 White from comment #3) > But NVIDIA..., most likely is Bug 782311. Is similarly, yes. But not sure if this is identical for me bug.

Oddly I don't ever see it happens for me on GMail ;p

Because this bug appear rarely, for me only scrolling in big conversations (e.g more 50 emails, e.g. bugzilla conversations). See in new screenshots attached.

If this is really the same bug as mine, firstly do some kind of test. If you see artifacts use shortcut CTRL+A for "Select All", if artifacts will be gone this bug is a dupe of mine so mark it as one.

So this bug is a dupe of my bug #782311. Please mark it as DUPLICATE. Thanks.
