ST7735S 0.96" 80x160 - black area #1269

I'm not sure if it's a problem with the library or not, but I have a strange problem and I tried a lot of things, but cannot solve it...

I have a cheap ST7735S based RGB SPI-LCD with 80x160 resolution driven by ESP32 dev board.

#define ST7735_DRIVER
#define TFT_WIDTH  80
#define TFT_HEIGHT 160
#define ST7735_REDTAB160x80 
#define TFT_RGB_ORDER TFT_BGR

With this setup above I got it partly working and showing correct colours. However, whatever combinations I've tried one part of the screen is always black. Maybe the display is damaged - I've ordered 2 of them and both show the same problem with the black area. Of course both displays might be damaged at the same time, but maybe you have an idea what to try else to get the full height shown.

seems both displays are broken. bought another one from another shop and it works perfectly with the same code.
