Installed swipl-10.0.0-1.x64.exe, SHA256 is correct.
OS is Windows 11Pro 25H2 with all updates.
Deleted previous installation.
Deleted preferences folder in (AppData\Roaming)
Reinstalled a few times but result always the same.
Swi prolog opens a window but the complete console displays only in the upper left quadrant. The other 3 quadrants are black.
Going full screen does resize the quadrants but the app still display only in the upper left quadrant.
