Hey Hackintosh users,

Ok, to be honest one thing that has kept me away from spending more time in OSX than XP is the cursor movement. As stupid as it sounds, something as simple as the pointer has kept me from fully adopting a better OS. As you can see from my sig i'm on an ATI AGP card with QE/CI, but experience the pain of mouse clipping.

 

The Mouse Locater hack definitely does the job for eating up most of the clippy bits left behind, but the responsiveness it takes out of cursor movement just kills the experience for me.

 

Enough beating around the bush, i think i've come across something which has *reduced* mouse clipping to a quite acceptable amount on my machine.

 

The major stumbling block in not accepting the tearing is that while scrolling a page (via mouse scroller) the entire area below the pointer is corrupted and goes up the screen until written over. Well, if that's you, i'm hear to say that I have gotten rid of this. If your mouse tearing isnt that bad, then maybe you've already somehow patched this.

 

First of all I'm going to admit that I'm not exactly sure what I did to do this. However, I can recite the steps, as it's not easy for me to go back and try to troubleshoot it myself.

Deciding to get to the bottom of how ATi's OpenGL driver was messing up, I downloaded ATI NVIDIA NVRAM Tool

(http://public.www.planetmirror.com/pub/majorgeeks/mac/video/T_ATI_NVIDIA_VRAM_V09.zip)

and checked out my vram usage. I left that running while checking out some XTools. I ran OpenGL Driver Monitor.app under /Developer/Applications/Graphics Tools and selecting the "Buffer Swaps" parameter.

Not finiding anything there I left it running and launched the OpenGL Profiler. This asked me something about installing a service or something to enable "Attach to Application". I did this then had to logout and back in, bringing me back to the same state. From there I tried to Attach to various programs including the loginwindow console and a couple others. None worked. I went back to teh ATIRadon9700GLDriver and brought up the Renderer Info (via File menu) and poked around. At that point I sort of figured I wasn't accomplishing anything and eventually rebooted.

 

Ever since then my clipping has been reduced enough that I find it acceptable. Whenever scrolling, the cursor disappears and little -if any artifacts are left behind they are deleted right away via a redraw.

The sad part is I don't remember doing anything in particular other than looking around to bring about this change.

...

 

Anyone stuck with the mouse clipping issue may be able to relate to the frustration and be interested in figuring this out with me. Personally I didn't feel like upgrading a video card that I liked, and now suddenly find myself with an OS that i can be comfortable with.

Having taken a test-drive of Vista I can definitely say I will not run that as my primary operating system, and look to OSX for the future of a good stable OS to do what I need.

 

Let me know anyone who's interested in figuring this out with me.

Cheers,

IAN

Hey, that sounds quite interesting.

I have a 128MB ATI 9800 Pro that works fine except for some annoying mouse tearing.

I bought a cheap replacement card, a NVidia 6200 with 128MB, just to get rid of the mouse problem. The ATI card was really ruining my OSX experience but I would love to get it to work, since it is much better than the new one.

 

Cheers,

Ok, for anyone interested i tracked down how to "eliminate" mouse tearing when using a scroll mouse.

 

By eliminating i mean that the window will redraw itself and not leave a trail behind -the point directly below the mouse still clips though. Upon closer inspection this seems to work in about 90% of the windows for some reason.

 

 

Anyway, run Open GL Monitor under \Developer\Applications\Graphics Tools.

Click the Monitors menu, Driver Monitors sub menu, and select your video driver. This will bring up a monitoring graph.

 

At this point something seems to load which affects mouse tearing in some way. Maybe a programmer can tell why, i'm really not sure.

 

Anyone else notice the difference? Or just me? I know i'm not imagining things....
