So, unless this is some weird compiler bug, I don't understand how trace-redisplay could have affected this. Although the fact that with a tool bar displayed you cannot reproduce the problem is already weird for the same reason. If you build with no optimizations (CFLAGS=-O0 ./configure...), but without --enable-checking=glyphs, does the problem still happen? > That's not the effect of 'checking', though -- I can still repro if I > don't turn on redisplay tracing (which prints stuff in the background > window; maybe it's relevant, maybe it's not). By "background window" you mean a shell window from which you started Emacs? Or do you mean something else?
