hi,
I am running the QML APP on TI DM8168/AM389x,with the arch ArmV7-a8.
The linux kernel version : Linux version 2.6.37+
graphics driver : TI Graphics_SDK_4_03_00_02
so, it is not clear for graphics driver specs -
the error is caused by the frame buffer setting :
Alpha : 255 represents a fully transparent color, while 0 represents a fully opaque colorbut the Qt5 is different :
Alpha : 0 represents a fully transparent color, while 255 represents a fully opaque colorso,I need to change the frame buffer setting for alpha;
anyone ideas ?
