#19161 new bug

Garbled KDL screen on UEFI boot without CSM

Reported by: Illen Owned by: nobody
Priority: normal Milestone: Unscheduled

Description (last modified by Illen)

KDL screen is garbled when Haiku is booted using UEFI loader with CSM disabled. When CSM is enabled (but still using UEFI loader), Haiku sets 1920x1080 mode instead of 2560x1440 and KDL sreen on such mode looks correct. This is just a minor issue as debug output on KDL is still readable.

Mainboard: Asus X570-Plus
GPU: Nvidia RTX 3060 12 GB
Monitor: Acer XV322QUP

Used Haiku hrev58212.
