I've recently installed Ubuntu 10.04 on a new i5 750 PC that has an ATI 5850 video card. I'm currently using ATI's catalyst 10.5 driver (directly downloaded from website).
I'm suffering from tearing. I bought a new machine to be able to use linux + Compiz and trash Windows. It seems, linux has a long way to go to appeal to desktop users (even if it's ATI's fault - 50% market share).
Whenever I move windows, I get tearing. This is really the most annoying part of it. Something as basic as moving windows should not cause tearing. Please remember that I am using Compiz, and wish to continue to use Compiz.
In addition to these tearing issues, full screen HD flash videos (using 64-bit v10.1 flash shared library) are extremely laggy. CPU usage goes off the roof.
Option "VideoOverlay" "off"
Option "OpenGLOverlay" "off"
Option "TexturedVideo" "on"
Option "TexturedVideoSync" "on"
Option "Capabilities" "0x00000800"
In Compiz, I have 'Detect Refresh Rate' disabled, Refresh Rate set to 60, Sync To VBlank enabled, and have disabled Unredirect Fullscreen Windows (weird things happen when enabled).
Can anyone please help me? Anyone with an HD5xxx card that is not suffering from tearing with Compiz? I mean even with compiz disabled, moving windows still has quick tearing - not as smooth as in Windows.
Also, if you watch the following youtube video set to 720p on full screen, do you experience any kind of tearing?
10-6 brings more Pink OpenGL fixes
10-6 Pink panther editions do have kernel 2.6.34 support so you can play HOMAM Heroes3 without kernel bugs!
the real 10-6 comes out if amd want to in the future or not no one know that right now...
Yeh, have same problem... - luckily the Open Source drivers work just fine from this point of view...
At this stage, I don't think 10.6 would help you but maybe they'll try to fix it, make this a priority for once.
The tearing is on even with compiz effects disabled so in this case is not related just to that. Yet I have a HD 4xxx not HD 5xxx so not sure if Open Source will work the same for you... but you might get there faster then I did 3 years ago when bought a HD 3xxx then HD 4xxx and now I finally see some results...
In my defense, back then I didn't bought those cards with Linux in mind... back then was only using linux as server, until I saw some improvement in Desktop environment - which got my attention (no, not compiz or other effects - but those are a nice bonus).
So unless you change that card with one from nVidia - I'd suggest you wait for better support from Open Drivers since FGLRX is not targeting the every day user, but the business part as in 3D workstations, so problems like this are not a priority.
Then again, who knows... maybe they'll fix it - i'm just talking from experience here...
I'm definitely thinking of returning the ATI card for an NVIDIA card. I'm not going to wait weeks, months or even years to get better support. It's 2010 damn it, not 2000. If that's how ATI wants to play, then so be it.
There's some discussion of tearing in Ubuntu in a recent (within the last few days including 1 day ago) of tearing with HD 5xxx cards using the fglrx driver. Whether the next driver ver., 10-6(?), fixes this remains to be seen but just pointing out this is from 2010, not 2009.
