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.
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:
Open Cursor Settings Cmd+,.
Search for “hardware acceleration”.
Uncheck Use hardware acceleration when available.
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.
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.
