When the OS is compiled without window system and with resolution greater than 1024x768 (e.g. 1600x1200 or 1920x1080), the graphical console display is corrupt.

On the other hand, display server works correctly in these resolutions and terminal, if its size is set to e.g. 1920x1080 by modifying the code, also displays everything correctly.

Resolution: fixed
Status: newclosed

Turns out this is a bug in output server's computation of screen dimensions. The output server allows a list of output devices and it computes screen size as the minimum across all devices. To compute the minimum number of rows and columns, variables are initialized with 128, 128, respectively. So if the screen has more than 128 columns, a lower value than the actual value is reported.
