Strange color change

[Tinkerpete]

I have written a small program which displays the values of an acceleration sensor as graphs. If the program runs for a moment, the colors suddenly change and pixels seem to be missing.

I was able to reduce the problem to the following small program. At least it shows the error that the color green suddenly turns red and pixels are missing.

#include <odroid_go.h>

void setup(void) {
GO.begin ();
/*
for (int x = 100; x < 220; x++) {
GO.lcd.drawLine(x, 80, 100, 159, TFT_GREEN);
}
*/
for (int x = 100; x < 220; x++) {
GO.lcd.drawLine(x, 60, 100, 179, TFT_GREEN);
}
}

void loop() {
}

The problem occurs only in connection with inserted microSd card!

Thank you for the issue. I will test with a microSD card.
