Describe the Bug I’ve been using Cursor for almost three months, and despite the hiccups, I’m still here trying to make us understand each other. But recently, since the last two updates, it’s become practically impossible to use. In addition to the already reported looping and default model halluci…

This should be resolved in v1.4.5 which was released today. [image] Supper laggy cursor after updating seems that my issues are resolved using 1.4.5 [image] Alex_Prucka: in short testing whatever was in Early Access seems to have improved it/fixed it for now [image] On another topic …

@saidattax @Jayant-WebDev Sometimes I ask myself fine, I can manage, but what about the Cursor employees who use Cursor to build Cursor? Doesn’t it freeze for them? Don’t they go crazy from it?

Yes we use Cursor every day to build Cursor. But this problem seems to be worse on Linux/Windows, and many of us use Mac. Even our Linux and Windows devs don’t see issues this bad for some reason :thinking: But we are investigating all these performance issues and have made many fixes already. Ple…

This was plaguing my team and I starting about a week ago, but in short testing whatever was in Early Access seems to have improved it/fixed it for now. Will update if that is not the case moving forward.

This happens to me aswell for a while now, freezes and lags in the software itself, takes ages for the AI to respond in the chats, looping in the chats and inability to complete a file-rewrite which fails over and over due to failure in Edit. this must be fixed asap.

Describe the Bug The latest windows feels significantly slow: mem usage up 33% from baseline workload frequent lag spikes on everything from syntax highlighting to +300msec on CTRL+P to find files cursor tab will leave residual completion as uneditable, empty space which only goes away after delet…

Can you tell us exactly what was changed ?

Thank you this build is so much better!

Yes 1.4.5 is MUCH better! I have still had it lag (pauses for a few seconds here and there) , and one time i had it completely lock up for about 20 seconds but it came out of it ok. It also still lags some when the agent is working , but it seems like the massive insane lag is gone or reduced eno…

I am still experiencing very sluggish UI, specifically on Window even at 1.5.5. How can I submit additional logs?

hi @GCosta lets debug first without logs. Do you have any processes running in terminal within Cursor? Does this also occur on a new project? (would indicate large chat storage) Does this occur when you run with extensions disabled? cursor --disable-extensions Please explain your usage more detai…
