My MDD G4 has two hard drives, one with Leopard (10.5.8) and one with Tiger
(10.4.11). I run Leopard 99% of the time.

1. After archiving and reinstalling Leopard and all updates, the cursor now
exhibits aberrant behavior. It frequently flickers on and off, especially
when using Photoshop, and also displays as an 'empty' square or string of
squares through which the background can be seen. I've researched this
problem thoroughly, but none of the solutions I have found have worked.

2. One of the solutions suggested was to reset the PRAM/NVRAM. When doing
this in the typical manner (holding down the Command, Option, P, and R keys
at start-up) from Leopard, the computer starts up in Tiger from the other
hard drive!

What's going on here????

Booting from the Tiger volume after PRAM Zap is normal, the startup disk parameter is stored in PRAM so it has been reset to a default value.

The aberrant cursor behavior doesn’t sound like a PRAM related issue. More likely it is a software conflict. Try creating a new user on the Leopard volume and see if the the same behavior occurs for that user.

I recently replaced the power supply on a G4 and just because it was
easy I checked voltage on the 15 V (something like that) lithium dry
cell on back-bottom corner of the motherboard. It was way below in
voltage and clearly printed 10 year lifetime. It's a half length triple
C and it wasn't hard to find in the neighborhood. It had been running
the clock while the machine was shut down.

Is there a CUDA switch on this machine? Did you press it?

I agree with Kris, this is most likely a video card issue, and may well be merely coincidental to the re-install.

Entirely expected if the Tiger volume is the first one on the bus. Clearing the NVRAM deletes the value holding the preferred startup volume.

If this machine does have a CUDA it is separate issue having to do with
hardware config.
Very often forgotten on the pre G3 machines.

If anything was changed hardware wise such a machine with a CUDA would not
see the current config but be set for an old one.

HD changes, memory, bus cards etc.
