Creative ZEN
Exether:
Hello,
I have exactly the same screen corruption as on the video on a 4Gb Zen of mine.

I have committed a fix for the screen, actually it's because I forgot to commit half of the errata by mistake last time. I hope it will work this time.

Hi all,
I have committed the new frequency scaling code and enabled it on the ZEN (and XFI). I don't expect any major problem here except that when switching frequency the screen might flicker once. Unfortunately, I don't see a way to fix this without compromising the battery life or performance. If you run in any serious issues, please comment so it can be fixed or reverted depending on the severity. Also if someone feels like doing a battery bench (even if approximated since we don't have plugins at the moment), it would be greatly appreciated.
ChronoSphere:
Thanks for the commits!
Do we have a battery bench of the non-scaling version? Or do we only want one of the one with frequency scaling enabled?
From what I saw, the non-scaling version manages approximately 10-12h with mpc@160kbps, but I'd be willing to do more tests.
An issue that was present prior to the display and frequency scaling commits, or rather, two:
- some covers either fail to display or only display in grayscale. Is there a size limitation for covers in rockbox? My covers are all 500x500 jpg@80% quality
- when going forward or backwards through the now playing list too fast, the controls sometimes hang and the player stops responding to any input. The music is still playing. After some time the commands are executed in very fast succession and the player is responsive again.
The two might be related if the code attempts to load the cover and fails, resulting in some kind of delay, just guessing.

Hi,
ideally, I would love to know: OF battery life, Robkox battery life (before and after frequency scaling), if you have any such figures for the OF, please share.
About your issue:
* The manual documents some limitations: http://download.rockbox.org/daily/manual/rockbox-sansafuzeplus/rockbox-buildap3.html#x19-374000C
* That's new to me, my theory is that the code is looking up some tags or something and begins being responsive again when it has the data. I'll try to reproduce it.
