What's new in v0.9.0-beta.2

A follow-up to beta.1, and only about recording. Everything else is unchanged.

You can now see that you are recording

There is a small red dot in the top left corner while a recording is running. It
pulses slowly, so it reads as active rather than as a stuck pixel, and it
disappears the moment you stop.

Until now nothing on screen told you a recording was running. RetroArch has no
indicator of its own, and it does not print a message when recording starts or
stops, so the only record of it was a line in a log file. On a handheld with no
light on the front, that meant the only way to be sure was to stop and go look
for the file.

The dot is not in your clips. Recording captures the emulator's own picture
before anything is drawn over it, which is the same reason a CRT shader never
appears in a recording. The indicator is drawn after that point, so it stays on
your screen and out of the video.

If you want to check that for yourself, record a few seconds and look at the top
left corner of the resulting MP4. It should be clean.

Testing notes

Everything from beta.1 still applies, and recording is still off by default
under Settings > Controls & Feedback > Recording.

For this build specifically:

• Does the dot appear as soon as you start and vanish as soon as you stop, on
  every system you try?
• Is it the right size and in a sensible place on your screen? It scales with
  the interface rather than being a fixed size, so it may look different from
  someone else's.
• Does it survive things that interrupt the picture: opening and closing the
  in-game menu, changing brightness or volume, sleeping and waking the handheld?
• Most useful of all: does the game run any differently with the dot on
  screen? It is drawn as part of the picture rather than layered over it,
  specifically so that it costs as little as possible, but a recording cannot
  reveal a slowdown to us afterward. If a game feels slower while recording than
  it did in beta.1, that is worth reporting with the system and the game.
• And confirm the dot is absent from the clip itself.
