On MacOS (Safari), I noticed that the geoguessr tab uses around 1GB of RAM when I start playing. As I play more rounds, (single player classic/community maps), the tab's memory usage starts creeping up by around 0.5GB per round. Once the tab starts using more than 9GB of RAM, the tab crashes and the browser reloads the page with a message that the site was reloaded due to high memory usage.
There seems to be a serious memory leak. I thought it could possible be due to my state streak / learnable meta extensions, so I checked again after disabling everything including tampermonkey. The issue is still present after disabling the extensions. I checked firefox as well, but the memory usage on firefox is stable at around 2GB. I think it is a recent bug, as I've never had geoguessr tabs crashing on me with this frequency before this week (2025-Oct-14).
