OS: Ubuntu 16.04 64-bit Intel® Core™ i5-2450M CPU @ 2.50GHz × 4

Got Arduino IDE 1.8.10 working after teensyduino 1.48 installer and programmed Teensy 3.2 on ttyACM0 with ‘VideoDisplay’ sketch from ws2811 examples folder.
Installed Processing 3.5.3

Strangely, just downloaded Processing on a Macbook pro and the same sketch runs fine with no errors
