LED panel with ICN2038S have graphical distortions #652

Hello! I have led matrix 128x64 with ICN2038S. It works well with the receiving card Colorlight 5A-75B. https://www.youtube.com/shorts/qVjnT78mICI

When I used the library I got graphic distortions on the panel. //my program configuration panel `HUB75_I2S_CFG::i2s_pins _pins = { 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 }; HUB75_I2S_CFG mxconfig( 128, // width 64, // height 1, // chain length _pins, // pin mapping HUB75_I2S_CFG::ICN2038S // driver chip );

mxconfig.latch_blanking = 4; mxconfig.i2sspeed = HUB75_I2S_CFG::HZ_10M; mxconfig.clkphase = false;`

ICN2038S: ICN2038S

Same program with ICN2037: ICN2037

What can be done to solve this problem?

Reduce the clock rate perhaps?
