If you encounter occasional flickering in some lights while actually controlling them, you can refer to the solution on the official MA forum:

Additionally: The maximum refresh rate of the DMX512 standard is 44Hz, and the refresh rate of our SL04 box is between 40Hz and 44Hz. If some older lighting equipment processes slowly and cannot keep up, it may occasionally cause flickering. If the flickering is caused by the lighting equipment not keeping up, you can connect such equipment through an intermediary device:

The DMX512 regenerator addresses issues associated with non-compliant DMX devices. Many lighting devices claim to accept DMX512 signals, but are unable to support the wide variety of timing parameters allowed by the DMX512 standard. The result is flickering, flashing, or erratic operation. The DMX regenerator addresses these issues by receiving any DMX512 signal, buffering the data, and then re-transmitting the data under a well-defined set of timing rules. In addition to this, the input is fully opto-isolated to provide protection and break potential ground loops.
We have found that most non-compliant devices can operate with a relaxed set of timing parameters. The output timing characteristics of the DMX regenerator are shown below:
Break time: 242 us
Mark after break time: 100 us
Number of slots: 512
Inter-byte time: 40 us
Mark before break time: 12 us
Refresh rate: 23 Hz
