ReactOS Newsletter 57 reports fixes that made the VirtualBox video driver more usable, including corrected mouse-cursor movement and screen-resolution updates. It also discusses RosBE and RBuild changes and a Windows GCC build issue involving compiler variables.

## Source excerpt

VBox Video Driver A while back the VBox video driver started working in ReactOS, which meant people using VirtualBox could now get hardware acceleration for graphics. To make the driver usable, Timo Kreuzer fixed two things in the Win32 subsystem. While the driver ran before the fixes, its functionality was somewhat crippled and drawing often resulted in problems. The first fix was for the mouse pointer, or more specifically drawing the mouse pointer moving across the screen.
