CAD view issue after using "ruler" mode

The Lumerical CAD view window is black after using the “ruler” mouse mode. Is there way way to bring back normal CAD view without restarting the program? Thanks!

Hi @xiaoge.zeng,

This sounds like a bug. Which version of the software are you using? what is your OS?

Please update to the latest version and let us know if the problem is still there. Thanks.

Hi @fgomez,

The version is 8.11.387, and our OS is Red Hat Enterprise 6.8. I’ll see if updating the software helps. Thanks!

Please try that and let me know if it works.

I have upgraded the software to the latest version (2016b, v8.16.966), however, the issue still exists.

Hi @xiaoge.zeng,

It is possible that the graphics card driver is causing the problem. Please try disabling the graphics hardware acceleration running the software with the command


as explained here.

Hopefully this will fix the problem. If not, we would need to know the graphics card and the driver you are using to try to reproduce the problem and fix it.

Hi @fgomez.

This problem has been solved by updating the mesa graphics driver. Thank you!
