same here on my mbp 2017,

Version: 47.0.2615.0 - Opera is up to date
Update stream: developer
System: Mac OS X 10.13.0 64-bit

always crash, wrong position of right click context menu, cannot select bullet in setting, cannot sync to opera, and bla bla bla many bugs.

And also please remove ctrl + space back to home as a default shortcut, we use this to change input method.

The new download page is great, however, the title of current downloading tab in Chinese should be "下載中" but not "即時書籤"(real time book mark). Please fix it.
