I don't know what's wrong here. Every now and then, Opera just stops to show the website, or more likely does not draw it. I can hover over the links and it shows me the link destination in the lower left corner, but that's it.
I don't know if that has something to do with using [testing] + [mesa-git]. I don't get any error message in the terminal. I have not encountered it in Firefox or Chromium, but in the Vivaldi beta (once). Also it never renders the bookmark preview correctly (it's just a gray box).
Any tipp about how to find out, what is going on?

I don't use Opera, but in Chromium, there's a known rendering problem that sometimes happens when the browser is maximized. If you restore or maximize the window, does it redraw correctly?

I'll try to maximize/"demaximize" the browser next time the problem occurs, though the problem here is: I never have Opera maximized. :-/

I hope this isn't considered necrobumping, but I have this same issue. If I lock the screen in Gnome and Opera was open, when I unlock it Opera stops rendering pages, it just shows a plank page where it's possible to hover over links and navigate blindly. I don't use any testing repo, though. There have been some Opera updates since this thread was created but the problem still exists. And maximize/restore the window does nothing.

And apparently the problem is caused by using hardware acceleration and an open source driver. https://forums.opera.com/discussion/com … t_15226326
There are some complains of opera not rendering pages correctly on their forums, and they offer as a solution using the proprietary binary drivers, and if that's not possible, then it's necessary to disable Hardware acceleration.

Well as for the "solution" with the proprietary binary drivers: That makes it even worse, because of another Chrome bug. -_- I'll try the "no hardware acceleration" thing.
