Welcome everyone. I couldn't find anything on the forum, so here is my problem. Writing software in Qt for embedded Linux 4.4.3 environment I came across following problem. The application contains quite much graphics, that is drawn on the screen by using a function drawImage(). All looks nice and neatly. However, to improve performance (since the software is being written for not fast processor), we started to load QPixmaps (managed with QWS) and draw them using drawPixmap(QPoint&, QPixmap&). Nevertheless some of the graphics are drawn in a wrong way - some assembles of pixels are not drawn at all, or are white. Moreover this is not a fault of graphic files itself, since if these images are shifted by few pixels, they are correct. Also, the same program compiled and run on Win XP or Mac OS X looks fine. Maybe some of You experienced similar problem or has any idea for overcoming it. We would like to use QPixmaps since they indeed get better performance.
Qt for Embedded Linux 4.4.3
QWindowsServer
graphic files PNG (not scaled in the program)
libQtCore.so.4.4.3
libQtGui.so.4.4.3
Thanks in advance for any help!
Chris.
