rename setBrightness to setPanelBrightness
...
For some strange reason it causes a panic. Some other arduino function must be conflicting.

Reduce / Remove Ghosting
...
After a lot of trial and error, I believe I've found the resolution to the ghosting, and it's as simple as reducing the brightness level to 60. The actual brightness doesn't change it seems, but the timing of the OE pin being set HIGH is performed earlier which can work better on some panels.

Current implementation simply write to the active DMA buffer, but you might want to use both buffers and do off-screen writes.

Disable auto back-buffer switch logic.

No point changing to the back-buffer automatically, should be for advanced/manual uses of the library.

Use something like:
' display.begin(R1_PIN, G1_PIN, B1_PIN, R2_PIN, G2_PIN, B2_PIN, A_PIN, B_PIN, C_PIN, D_PIN, E_PIN, LAT_PIN, OE_PIN, CLK_PIN ); // setup the LED matrix'
with R1_PIN etc. referring to your own define or constant variables
