Hello Am i the only one who observed very bad performance since updating to today’s update on windows 10 ? I can’t seem to work in correct conditions due to strong IDE lags, i’m thinking of temporarily switching to sublime the time it’s solved (yes it’s that bad). I wonder if i’m the only one havi…

After updating to 2.6.11, I noticed right away that the program was running awfully slow, after a couple of prompts and basic operations RAM usage skyrocketed to 5GB+ (and climbing lol) with CPU usage hovering around 20-30% which points to some sort of memory leak.

[{ABB36EEA-B3AF-44E4-BF9E-579523CE184E}] I’ve been using Cursor for a month straight. I’ve never seen this happen. I think they should rollback this update - there is something wrong.

Hey, thanks for the report. It looks like this might be a regression in 2.6.11. Today we’re seeing similar messages from other users too. The agent is showing full file rewrites in chat code blocks instead of minimal diffs, especially on larger files. A couple questions to narrow it down: Which …

Where does the bug appear (feature/product)? Cursor IDE Describe the Bug I’m experiencing an issue where the AI code suggestions are overwriting the entire file rather than applying specific fixes. Every time a change is suggested, the tool deletes all existing code and replaces it with a new block…
