Cursor is having serious UI issues at our company to the point that we’re considering dropping it. This seems related to the length of the current chat, not number of chat histories, at least as far as I can tell. I’m guessing there’s excessive processing of something like rendering the entire chat or something along those lines. It’s almost impossible to work once you get to this stage.
Steps to Reproduce
I’m working on a C++ codebase, but it happens in other contexts as well. I’m using claude-4-sonnet, in case it’s related. The longer the chat history for the current chat, the worse UI responsiveness gets.
Operating System
Linux
Current Cursor Version (Menu → About Cursor → Copy)
We’re using either Ubuntu 22.04 or 24.04. In general, we experience a lack of UI responsiveness that appears to get worse as the length of the current chat increases, but I can’t say for sure. In my personal experience, clearing the current chat helps significantly. It gets to the point where linux/gnome keeps reporting that Cursor has stopped responding and offering a force quit. It starts occasionally and eventually the popup comes up every second or so and any input into Cursor becomes impossible.
Now that I know about the Console, I’ll post it once I get into that state again – currently it’s full of historical junk.
We have made today a pre-release where beta test users confirmed bug fixes and improvements in performance. An update is coming soon for all Default channel users.
