Blank new tabs
Vivaldi 1.5.658.56 (Stable channel) (32-bit)
When I want some link to open in new tab(middle click) it loads but page is blank. It only occurs with middle mouse button. Right click works fine for both foreground and background opening.
It doesn't happen with all links, only some specific, like http://9gag.com/. When I open some image in new tab, it looks like that:
I can also click links and other elements even if I don't see them.
Mouse middleclick works for me with 1.5.658.56, on 9gag picture opens in Background tab.
You can try updating to the latest snapshot (currently 1.6.689.13)
There was some old thread about it, some solved it finding they had an extension which was causing the bug, some by adding an option to disable the GPU
--disable-gpu solved the problem
