Yarotows means "Yet Another Rewrite Of The Old Win32 Subsystem", it's being done in a branch, and will be merged back to trunk once stable enough. It targets better compatibility with Windows, specially with DDI and loading and unloading drivers.
- Animation in file copy dialog (comdlg32) is not shown anymore (in trunk it shows a black background, see #2261)
- VBox addons regression (not verified)
- Fullscreen color issue
