I also have this problem on the Fedora 28 Mate Spin (I hope it's okay to put that here). I routinely set the clock to show the seconds and that really uses up the memory. Note that with absolutely nothing "refreshing" the screen there is still some leakage. I have been using Fedora since version 3 and I have never seen this before. For example, I have a Fedora 27 Mate laptop that has been running for 381 days, no leaks of any kind.
I have several computers to test things on and so if I can be of any help on this please let me know. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1793465 Title: Mate Panel consumes huge amount of memory even when idling To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mate-panel/+bug/1793465/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
