Troubleshooting
LumaSpace uses too much memory
LumaSpace targets under 300 MB of RAM. If you're seeing more than that, the cache probably grew during a long session.
How to bring it down
- Close the main window if you're not actively browsing. Previews load wallpaper content into memory, and closing the window frees that up.
- Go to Settings > Cache and clear it.
- Go to Settings > Downloads and clear if you've got a lot of saved wallpapers piling up.
- Restart LumaSpace — it trims memory buffers on launch.

After these steps, usage should settle back under 300 MB.
