Marble Pysical Memory Setting returns 0 (zero) when setting higher than 2047 MB ... in program itself and marblerc configuration file after restarting Marble with setting physical memory limit higher than 2047MB (like 2048MB). Testet several times. Marble Version: Version 1.12.20 (1.13 development version) Disro: Xubuntu 16.04 LTS (fully updated)
Confirmed for Marble 2.2.20 (2.3 development version) using KDE Frameworks 5.71.0
Ouch, yes this likely results from the fact that the setting is specified using an integer that refers to the bytes. I have a refactoring in the works for the FileStorageWatcher which should take this into account.
