1. open lib/fonts/test/stmary10.lyx 2. go to preferences->display 3. instant preview->off (from on) 4. apply 5. kaboom
I can reproduce on qt4, not qt5. On commandline: CoordCache.cpp (30): break on pointer: 0x96ff0e0 hint: dim size: 0 For some weird reason I can't get meaningful backtrace. Anyone can? Pavel
