[Solved] Opera visual glitch

About half the time (or more) I open a new tab in Opera it looks like this:

When this happens, LastPass becomes unusable. Sometimes it refuses to display any pages whatsoever, instead showing only a blank page.

I've tried disabling all the extensions and deleting the cache. One time it started behaving after I deleted ~/.cache/opera/ and ~/.config/opera/, but it didn't last long.

You might be able to get LastPass back by going into the extensions and turning it off and on. The main problem, no idea.

I filed a bug in Opera's bug tracker. After a few updates, the problem seems to have gone away. Hard to say what happened since I can't find it now.
