Was something done to keep folder icons smaller in Nemo? After last upgrades, the folder icons in Nemo had become smaller. The changes in Nemo preferences don’t hold at 50% after reboot/logout.
Nothing has changed in that area for a few weeks.
Just tested v3.8.5 nemo (the default in 19.04) and the List View preferences stay at whatever percentage you set it at after a logout/login.
All right. Might be just a one time problem.
