With the very latest iteration under Linux (MX19) I find the blank screen issue as has been mentioned variously in (closed) topics here.
- launch BB normally
- view a video on youtube
- click on home page (or any other web address) away from youtube
- black screen
- black screen does not crash the browser but the browser won’t be usable until the mouse is moved.
This happens on two platforms and in Linux as mentioned above as well as Windows.
