when laser playing appears some lightspots
I read ILDA file ,as the coordinate data are 16 bit,so I have to convert them into 8 bit(My Hardware just support 8 bits resolution),just divide 256. When play an animation ILDA file,some lightspots appear.but if playing an statical ILDA file with Pangolin,it didn't happen. I don't know how the lightspots emerge.
Can anyone do me a favor?

I'm going to assume is a parallel port driven 8 bit DAC:
The "hot spots" are basically lock states where the processor has something else far more important to do than flip line levels over a parallel port.
To verify: Do something with the computer that is IO and processor intensive.
With the laser display running open up a command line and type in dir/s or run something super saturating like a program that calculates Pi.
