Visit some non-trivial file that compiles with no warnings: emacs -Q some-file.el M-x byte-compile-file RET RET During the resulting compilation, at some point it looks like the Emacs display goes completely blank. It happens a bit fast, so it is hard to say exactly. It does not look to me as if it is switching to another buffer (Compile-Log) and back again. It's like the display flashes off and on. The tool-bar, mode line also disappear. This effect does not happen with 24.3.
