gpu: texture caching issue
I see
(gtk4-node-editor:716438): GLib-GObject-CRITICAL **: 23:25:41.770: g_object_weak_unref: couldn't find weak ref 0x7f9afc71c871(0x5a76bd0)
coming from the gsk_gpu_device_cache_texture_image call in GskGpuFrame.
Not sure if it is related, but the docs for g_weak_ref() point out that it isn't threadsafe and we should use GWeakRef instead.
