I'm experiencing issues when using nightly builds on my rpi4 4gb. Since build LibreELEC-RPi4.aarch64-12.0-nightly-20230901-c3d17f9.img.gz the memory usage is permanently increasing until kodi reboots.
Last working build for me is LibreELEC-RPi4.aarch64-12.0-nightly-20230829-db892cd.img.gz.
Please tell me if further infos are required (logs,...)
