Anyone else notice this bug?

[Complex Pants]

So I was just messing around with my Xoom and I noticed something interesting. If you keep your Xoom uprighte (camera at the top in landscape) it has very smooth animations when on the home screen. However, if you hold the Xoom upside down (camera on the bottom) the frame rates seem to drop and things looks jerkier.

Anyone else get this?

I am using a stock, unrooted Xoom wifi.

I'd be jerky too if you held me upside down

I tried that on mine and didnt notice a difference...I am on a TIAMAT kernel wth the OC GPU...maybe thats it..

From what I've been reading in the forums, its that way with every xoom :-(

I wonder if it is software or hardware.

Hardware. It's a Tegra 2 issue. There was supposed to be a software fix/workaround in 3.1 but it didn't happen. The issue is still up on the Android bug tracker marked as fixed in a 'future release'.

At this point I'm guessing that the future release will be called Tegra 3...

Ah thanks. Glad to know it isn't only me and sorry for the post of old news. I just noticed it today

Do you have a bug number for this issue?

Afraid not, but if you Google something like 'honeycomb lag portrait mode' you should find it.

I still think it's just a software issue that Google hasn't gotten around to. There aren't any performance problems with orientation on hardware far inferior to Tegra 2 after all.

Maybe some manufacturers have fixes for it, like how Samsung had a hardware accelerated browser before Google added it to the stock browser in Honeycomb.

Well hopefully it is a software issue. The best way to tell is if the Transformer, Iconia, or Galaxy 10.1 have this issue as well. Since they all essentially run the same hardware.

 

[deejayd]

at I/O they said it was a problem with honeycomb running on 'specific hardware'

So it's likely a combination of both. Tegra 2 might not fully support some aspects of the honeycomb code.

I'm inclined to think that if this was a simple software issue it wouldn't have survived this long.
