Problem is probably caused by graphics stack and gles which apparently does not handle access from multiple threads. When I exported QML_BAD_GUI_RENDER_LOOP=1 almost all applications works(ex. Qt Conematic experience). Problem is with static applications (red rectangle) without any animations - it looks like only part of the window is drawed. So as for now - SOLVED. -- Pozdrawiam/Regards, Tomasz Olszak
