Same problem here. Only solution is to restart Opera.

Running Opera Version:56.0.3051.52 on Mac OS 10.12.5

This has been happening across many versions of Opera and Mac OS. I have seen the same behaviour on my Windows 10 laptop.

After a while particularly in full screen or split screen mode the page will move up by differing amounts. That is the top of the page will become cut off by the amount it is moved up. Sometimes a whole line or 2 or part of a line (1/8 to 1/2 inch).

When this happens i must click below any link or select below any text by the amount the page is 'moved up'.

If i refresh the page the same behaviour exists. The only solution is to restart Opera.

This really interferes with workflow. This does not happen btw in any other browser including Chrome, Firefox, or Safari.

I would like to be able to create a new tab to the right of the current or certain tab and not at the end of all tabs. A right click command on a tab (Create new tab to the right...) and a keyboard shortcut would be great.

Thanks
Jacob
