screenshot of allegro viewer showing blank viewer pane
Xquartz beta 2.7.9 doesn't work with Allegro Viewer. Opening a board file always results in a blank view.
XQuartz 2.7.8 on El Capitan works fine.
To do this, I use either Exceed or just ssh -Y into the remote unix machines, and then launch the GUI Allegro Viewer application, which opens its windows using XQuartz. I downgraded and it's working again for me.
Please test 2.7.9_rc1 when it is out later this week. I wonder if the fix for bug #93318 will address this as well.
If not, we need to figure out exactly which change is causing the problem.
my colleague tried 2.7.9_rc2 and still has this issue
