Where does the bug appear (feature/product)?
Cursor IDE
Describe the Bug
Random severe flickering occurs in the content output area of the right Agent panel during normal use in editor mode. The AI response text area refreshes rapidly and flashes repeatedly for no obvious trigger.
My hardware and system environment: 2K 2560*1440 monitor, Windows display scaling set to 125%, Windows 11 Pro.
This issue happens sporadically and is not tied to a specific window or sidebar width; adjusting panel size cannot reliably reproduce or eliminate the flicker. There are no custom themes, modified UI settings or conflicting third-party extensions causing this.
Steps to Reproduce
1.Open Cursor IDE and stay in standard editor mode
2.Keep the right Agent chat sidebar open for regular chat interaction
3.Interact with Agent normally (send prompts, view generated replies)
4.The output panel will randomly start continuous flickering spontaneously
5.The flicker may persist for a while, then disappear on its own, or temporarily stop after dragging the sidebar divider (but the bug can reoccur randomly later)
Expected Behavior
The Agent chat panel content should render stably at all times without spontaneous, random flickering of output text.

Does this stop you from using Cursor
No - Cursor works, but with this issue
