Symptoms:

• resolve only working in 5-10% of the times (looks like race condition)
• scrolling becomes unresponsive

Environment:

• 2 different eclipses (different folder, different instances opened) (cause seems to be outside project, outside eclipse)
• 2 different Spoofax languages (webDSL and relations language)
• however non-spoofax eclipse editors were fine

Tried (didn’t work):

• closing projects
• cleaning projects
• restarting eclipse

Fix:

• restart OSX

So it seems to be a combination of the way Spoofax does UI and a screwing up in the OSX display manager. More precisely I disconnected my laptop from the thunderbolt display and connected it the HDMI beamer, that is when I first noticed the that scrolling was unresponsive.

Does this only occur after changing the display configuration?

I dont know, I have not been able to reproduce this.
