YES because I tested if quota and qgroups disabled would help.
And yes I am aware of that, since I deleted them and only did one ‘snapshot’ with no qgroups and quota so timeshift cant know the size. (At least that is how I understood btrfs and qgroups and quota)
EDIT:
I forgot I also tried to disable baloo file indexer, also with no results.
Also tried disabling Compositor.
