Designer and perspective project style problem 8.1.38

Hi,

I've been having an issue with how my project looks in the designer versus how it looks in the browser when the project is open in Perspective (Ignition 8.1.38).
The problem is that what you see in the designer is different from what you see in the actual project. Since multiple people are working on the project and we use version control, the thumbnails have been changing, and a few weeks ago the project ended up with this weird style in the views shown in the designer.
The strange thing is that this is only happening to me; my colleagues haven’t been affected by this.
Does anyone know what might be causing this? I’ve already reinstalled the designer and the Perspective module.

In the Designer:

In the perspective project:

And this happens in all the views of my project.
Thank you in advance for your advice

Someone probably added something to the advancedstylesheet that is affecting views globally. If it's only affecting you then did they push some font as the default that you don't have installed?
