Quade node splashing

hello,

i have an info texture for the service people to calibrate the serial device to the 0-point. I am doing this with an onopen node and an flipflop. when the serial input is 0 the Quad with the texture fades out. this part works fine. but sometimes in fullscreen mode the texture flickers in… on the same group there is an dxt4 animation… is this a problem

regards.

what again is a dxt4 animation?
