Ubuntu - Strange display issue (this leg only)

Hi,

I was testing OpenCPN on Ubuntu using a Ubuntu guest on a WIN10 host (VirtualBox).
Everything seems to display fine except the "this leg" window when activating a route, it is all black with no display, not even the dashes ... (see attached picture).
OpenGL is working fine. With tactics plugin which requires OpenGL to run, everything is displayed correctly.
NMEA stream is coming from an other openCPN on the network.
I am not sure it comes from using Virtualbox, as long as everything else is displayed as it should and I have never have any display issues with any software on this Ubuntu.
I have no clue of where it could come from.
If you do ... please share !

Cheers.
J.

Options > User Interface > Fonts > Console Value


What color is it?


PS: I don't think that is the text in the Console, because it does not seem to change.
No access to the manual, so you will have to check that yourself.

Re: Ubuntu - Strange display issue (this leg only)

I run a Ubuntu host with dark window themes and Windows clients using the standard Windows themes and have noticed that the Ubuntu theme occasionally "bleeds" through to the client which I suspect is a VirtualBox bug. The other issue I notice on my system with Ubuntu and OpenGL is that it can slow the screen redraw in OpenCPN to excruciatingly slow if another app using OpenGL has is already running (like Google Earth). This latter issue doesn't seem to be a problem if OpenCPN is opened first.



I've got an NVidia graphics card in this machine, though, and this may be the root cause of the above issues.
