Hello Community,

I am having trouble with my Gazebo user interface. When I first boot my computer, Gazebo works fine, and will load a blank map when I ask it to. However, if I ever restart Gazebo for any reason (close out and start again, etc.), the user interface glitches out. Instead of seeing a gridded map as usual, the gazebo screen appears black. I can still insert models and delete models and edit the environment, I just can't see what I'm doing.

When I run dmesg in the terminal, I get this line that I suspect is the root of the problem:

[  605.908616] gzclient[2329]: segfault at 4 ip b6adada9 sp bff9b8a0 error 4 in libQtGui.so.4.8.1[b64d9000+aaa000]

EDIT:

I tried logging out and logging back into my user, then running gazebo, and got this error:

Can anyone tell me what the problem is and how to fix it, or at least give me some leads on how to solve this?

Thanks, skyguyjedi
