The Chat in Cursor IDE is BLINKING when the vertical scroll is at end (much faster than this git shows).
If I scroll to top it stops.
If I close and re-open Cursor and if if it was blinking, it will open blinking.
Steps to Reproduce
It kind of random, but I ask something and it starts blinking before the full answer, or at the end of it.
Hey, thanks for the report and the GIF. The recording clearly shows the flicker during streaming.
This is a known issue with chat flickering on high-DPI Windows. It’s often related to GPU hardware acceleration in Electron. Can you try this workaround?
Open the Command Palette with Ctrl+Shift+P
Run Preferences: Configure Runtime Arguments
Add this to the file: "disable-hardware-acceleration": true
Fully restart Cursor
If that doesn’t help, also try:
Lower Windows display scaling, for example 150% → 125%
Update your GPU driver
Stay on the latest build
Let me know if disabling hardware acceleration helps. That’s a useful signal for us. I can’t share an ETA for a fix yet, but it’s on our radar.
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.
