GAZEBO does not scale the map to the entire screen

Hi Gazebo Team,

I installed gazebo on my Ubuntu system today.
But i noticed that the map i want to use doesn't scale to full screen.

Maybe someone has seen this behavior before.

Have you solved it? I also have this problem, Ubuntu20.04 + gazebo11. After investigation, it was found that there was a problem with the display scaling of the Ubuntu system. When the scaling ratio was adjusted to 100%, it became normal.

Hi @renyuhui0415,

I didn't solve it.
I upgraded to Ubuntu 22.04.
But in the future I will use Ubuntu 24.04 or OpenSUSE.
I don't want to use X11 anymore.

Hello, I have solved this problem.
I found a solution in other issues. Due to HidPI, I need to add the following two lines of code to .bashrc file.

export QT_AUTO_SCREEN_SCALE_FACTOR=0
export QT_SCREEN_SCALE_FACTORS=[1.0]
