I have an ESP32 project using SmartMatrix that works well for several hours. When I come back to it, the update speed has dropped, and according to my logging, the refresh rate has dipped form an initial 85Hz to a mere 19Hz.
Can anyone tell me what would cause this? I’m not seeing evidence of a memory leak. It takes hours to manifest at times, and the only other symptom is CORE_1 is very busy (my drawing is on CORE 0, and I am NOT passing SMARTMATRIX_OPTIONS_ESP32_CALC_TASK_CORE_1).
