What is GSK? Was there an official Fedora change for the switch to Vulkan?
That would be the GTK Scene Graph Kit (part of the rendering pipeline in GTK?) . It's an upstream change, so I am not sure if a change is needed (I am not saying it's not, just don't know). They've (GTK upstream) made a change from gl to ngl renderer in Fedora 40 [0] (there was an issue on RPI 4 caused by it that got resolved before the GA [2]), and the current devel version of GTK 4 in rawhide changed that once again from ngl to vulkan.
