Many app developers have complained that even within Gnome, apps developed using GTK get a very high number of bugs that are caused by unique customizations that the user may have installed and no one else does. These bugs, despite being significant in number, consume an even more outsized amount of resources and energy because they are very difficult to reproduce.

System76 is only adding to that mess.

"Significant in number" is a funny way of writing statistically insignificant.
