About an unknown parameter while routing differential pairs

[mulfycrowh]

Hi everyone.

I probably touched something.
The issue occurs when I route differential pairs.
Everything becomes black and then it is very difficult to know where to go while routing.
Thanks for help.

Important to say:

1/ If I drag from an existing part of the differential pair, it is OK
2/ If I use Interactive Differential Pair Routing, all the environment turns black

Graphics card or drawing problems? How is 3D?
Restarted PC?
Does everything go black of just the nets in question?
You could save your preferences and restore (all) the defaults. If it still happens....
Today my colleague noted that sheet entries were misbehaving on the latest 23.8 version AD. My 23.7 is ok. The is no direct mentioning of it in the release notes.

I restarted the PC many times since the issue.
Is there one parameter in the Preferences that could trigger this behavior?

Here the screenshots when OK and black.

did you try press [ or ] repetitively? maybe the mask setting are on the maximum?

This is not black, it is either masking or dimming. Seeing the preference it would be masking.
You can switch this off or as robertferanec mentions, change the mask level.
