First, I have to say OSC Master-Slave is not an officially supported config.
Now, that's out of the way...

Which Resolume versions are on the sender and receiver?
Is the GPU's maximum supported texture size the same on the machines?
Resolume takes the GPU properties and sets some of the parameter min and max values base on that.
For example the Transform position x, and y are such params. Check the max value you can set for this, and you should get the supported texture sizes.
Now, when you send such a parameter via OSC, the value will be a float 0-1 representing the phase between the max and min value. If the texture sizes then differ, the max an min will different, and the same value will be a different float.
I'd recommend setting up a specific OSC shortcut preset on the master, to only send the data you really need.
