### Where does the bug appear (feature/product)? Cursor IDE ### Describe the Bug The UI gets broken / corrupted and is unusable. Parts of the IDE screen disappear (most of it), other parts remain, other parts are garbled. Only solution is to quite Cursor and reopen. ### Steps to Reproduce Seems to happen mainly when I am using Cursor normally, lock my screen, then come back to Cursor. It’s not easy to reliably reproduce, but it has happened multiple times across different Cursor versions. ### Expected Behavior Parts of the Cursor UI disappear; others remain but in part; the terminal text gets garbled. See attached screenshot. Bits of text and UI appear when hovering over it. Other parts were blinking on and off. ### Screenshots / Screen Recordings ![Screenshot 2025-12-20 at 2.53.21 PM.png](https://us1.discourse-cdn.com/cursor1/original/3X/0/e/0e3363ac188d685e4f56747af4ec6e2254d76b71.jpeg) ### Operating System MacOS ### Current Cursor Version (Menu → About Cursor → Copy) Version: 2.2.43 (Universal) VSCode Version: 1.105.1 Commit: 32cfbe848b35d9eb320980195985450f244b3030 Date: 2025-12-19T06:06:44.644Z Electron: 37.7.0 Chromium: 138.0.7204.251 Node.js: 22.20.0 V8: 13.8.258.32-electron.0 OS: Darwin arm64 24.6.0 ### Does this stop you from using Cursor Yes - Cursor is unusable ---

Hey, thanks for the report. I can see the screen corruption in your screenshot. This is a GPU rendering issue that can happen on macOS, especially after locking and unlocking your screen. Please try this workaround: 1. Open Cursor Settings `Cmd+,`. 2. Search for “hardware acceleration”. 3. Uncheck `Use hardware acceleration when available`. 4. Restart Cursor. This disables GPU rendering and should stop the corruption. If the issue still happens after disabling hardware acceleration: - Launch Cursor from Terminal with `cursor --disable-extensions` to rule out extension conflicts. - If that helps, check `Cmd+Shift+P` \> “Developer: Open Extension Monitor” to find any problematic extensions. Let me know if this helps. ---

Thanks for the quick response, Dean. I looked for hardware acceleration and only found a setting “Editor: Experimental Gpu Acceleration” which was already off (screenshot). But for “acceleration” there was also “Terminal › Integrated: Gpu Acceleration” which was on; I have turned that one off. Will report back if the screen corruption happens again. ---
