In Manjaro 18.1.5 (kernel 5.4.12-1 and 4.19.96.1, XFCE 4.14.3), not only chromium 79 is affected but also firefox 72.
In chromium 79 it closes at approximately 10-15 seconds, unless we deactivate the sandbox.
In firefox 72 a process called IPC LAUNCH # 1 appears, which does not close when closing firefox, consuming a lot of RAM, because several of these processes are generated at the same time.
