I'd guess it also misbehaves if you use `g' in the compile buffer (in
which case the output is placed in the current-buffer), because IIUC the
problem is that idle-timers (such as used by jit-lock-defer) are not
restarted after running process-filters.

While we should fix this bug, we should also fix the performance problem
that caused you to set jit-lock-defer-time (so please, report this
problem via M-x report-emacs-bug).
