[graph-tool] Memory error with fit-view and vertex text

Hi, I have a problem with the following code here: https://gist.github.com/FlxVctr/0be83561c6c423222c3fb0799c606667 As soon as I try to fit-view or resize the text I get a memory error even though I have more than 30GB RAM available. Does this functionality rely on GPU memory? Cheers, Felix
