Is there anyway yet known to prolong the strange problem clearing memory erasing cache something?

It seems that memory intensive apps can cause issues, as prolonged use of Photoshop CS3 causes this bug too. Adjusting the memory/performance settings within PS itself can stave off the bug for a while longer, but eventually it catches up. It's the only app that causes this for me which is a great shame as I use PS quite a lot.

Hi,

I am running Leo4all v3 10.5.2

I also had this issue, but when i switched from PCI WiFi card (D-Link DWL-G510 Rev c) to the USB WiFi stick(D-Link DWL-G122) , the problem solved.

Xbench score = 155 (Without Disk Test)

Xbench Score = 122 (With Disk Test)

My sys config::

AMD Athlon FX-60 @ 2.6 GHz
Asus A8N -SLI Deluxe
2 GB Mushkin DDR500 Ram @ 400 MHz
eVGA 8800GT SC 512 MB (GFX-String with NVinstaller.41 and patched Div ID Files, QE / CI Enabled)
Asus SATA DVD-RW
Seagate 250 GB SATA II HDD

One more update :
For people who having Logitech Mouse, there is Logitech driver and control utility for Mac OS x on Apple's site.

I found serious improvement using my Logitech USB keyboard/mouse.

I only notice the mouse stutter bug when I am transferring large files, across HD's for instance. Otherwise everything works great. Is it something to do with the ata/sata drivers?

Same on mine. I got a DFI Lanparty Nforce 4 SLI-DR.
Just switched it to 1.1
Will report back on what happens.

one more suggestion, in motherboard BIOS, try changing your ACPI -APIC settings. Try S3.

Avoid S1 and S3 together.

System running for 30+ hours now. One Firefox crash (probably website related).
No mouse movement bug though as yet.

Unfortunately about 5-6 hours later, the mouse movement bug reappeared along with some weird behavior in Safari and segmentation errors repeatedly crashing Adium.
I changed the ACPI settings to S3 but this didn't seem to help.
Installed the 9.2.2 kernel, and though the system felt a little smoother - the mouse bug was still persistent.

Would this bug show up if I install leo4allv3?

I am using Leo4all v3, and i have no problems, so i guess you can give it a shot.
