This patch ensures that the displayed pixel buffer is always consistent by applying intermediate drawing steps on an invisible back buffer, which is blitted to the front buffer by the GUI server. Note that the addition of the back buffer increases the decorator's RAM demand by 4*w*h (4 bytes per pixel) whereas w and h are the screen size. Issue #5350
This directory is a source-code repository containing Genode-specific services and applications. In contrast to the components hosted in the 'os' repository, programs contained in 'gems' are able to leverage the functionalities provided by higher-level repositories such as 'libports'. To use the 'gems' repository, make sure to also add those repositories to your build configuraion.
