- Lintlafatso ho sistimi e nyane ea KVM/Hyper-V.
- Mokhanni oa virtio-gpu hona joale o tšehetsa papiso ea EDID bakeng sa li-monitor tsa sebele.
- Mokhanni oa virtio_blk o kenya mohala oa ho lahla.
- Likarolo tsa ts'ireletso tse kentsoeng bakeng sa memori ea NV e ipapisitseng le lintlha tsa Intel DSM 1.8.
Bakhanni ba Lisebelisoa:
- Liphetoho ho DRM API ho ts'ehetsa ka botlalo khokahanyo e feto-fetohang (karolo ea maemo a DisplayPort) le litefiso tse feto-fetohang tsa ntlafatso (karolo ea maemo a HDMI).
- Tekanyetso ea Display Stream Compression e kenyellelitsoe bakeng sa khatello e sa lahleheng ea melapo ea video e lebisitsoeng ho li-skrini tsa qeto e phahameng.
- Hona joale mokhanni oa AMDGPU o tšehetsa FreeSync 2 HDR le GPU reset bakeng sa CI, VI, SOC15.
- Mokhanni oa video oa Intel hona joale o tšehetsa li-chips tsa Amber Lake, YCBCR 4: 2: 0 le liforomo tsa YCBCR 4: 4: 4.
