Cursor windows app completely blank after loading

sst4460 · January 13, 2026, 4:13pm

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

I have been using Cursor IDE on Windows without issue for about a month now. Suddenly today every time I launch it I just get a blank window with nothing in it.

Steps to Reproduce

Open cursor.exe

Expected Behavior

cursor should load normally

Screenshots / Screen Recordings

Operating System

Windows 10/11

Current Cursor Version (Menu → About Cursor → Copy)

can’t access about but .exe says 2.3.29

Does this stop you from using Cursor

Yes - Cursor is unusable

sst4460 · January 13, 2026, 4:16pm

Issue persists after upgrading to 2.3.34.

And “use-angle”: “gl” does not fix it.

Hey there!

Probably need to have a look at the logs.

Could you:

Press Win + R to open Run dialog
Type %APPDATA%\Cursor\logs and press Enter
Look for the most recent timestamped folder
Zip it up and attach it to your next post?

viv · January 13, 2026, 4:36pm

Yup i am facing similar issues. Coming here directly after Cursor refuses to load the remote server. I killed the remote server session but it seems to stuck in a loop of not showing anything. I have attached ss of what i am seeing.

I am on Ubuntu22.04. Seeing the same thing, seems to be a common build issue.

sst4460 · January 13, 2026, 4:40pm

I blew away my Cursor folder in AppData and that seemed to fix it. Not ideal but it’s running again.

Colin · January 13, 2026, 4:41pm

@viv If you haven’t blown away your application data yet, could you try pulling those logs? On Linux they should be under ~/.config/cursor/logs/

sst4460 · January 13, 2026, 4:43pm

I actually saved my old Cursor folder. This might be the relevant error in render.log (not comfortable uploading the entire folder):"

viv · January 13, 2026, 4:49pm

is there any other way to send you this log? i dont want to upload my telemetry data to public forums!!

Colin · January 13, 2026, 4:51pm

I’ve sent you a PM!

Ivan_Zidov · January 13, 2026, 7:21pm

For me, it completely freezes. Can’t do anything.

viv · January 14, 2026, 8:04am

Yeah i had to purge the whole thing and reinstall from scratch and go back to 2.2 until 2.3 becomes stable.

real-napster · January 14, 2026, 8:06am

Same here. Same Error as @sst4460
any solution @Colin for me?

Colin · January 14, 2026, 8:14am

Hey all!

Thanks for the follow-ups here.

While we dig into the root cause, can you try loading Cursor with cursor --disable-gpu to see if it takes you past the blank screen? cursor --disable-extensions would also be good to test, to rule out any issues with third-party extensions.

CMDK · January 14, 2026, 12:14pm

cursor --disable-gpu
This worked for me (win 11), then I could upgrade to 2.3.35 and it works from normal startup.

Colin · January 14, 2026, 1:20pm

@real-napster @viv @Ivan_Zidov Could you see if this helps you as well?

real-napster · January 14, 2026, 1:47pm

its kinda strange: i mainly use the “open folder” function. some folders open, one specific folder wont open, even with the --disable-gpu option.

Are you still at 2.3.34 or has Cursor updated to 2.3.35?

Ivan_Zidov · January 14, 2026, 1:51pm

Worked for me also!

real-napster · January 14, 2026, 2:07pm

v2.3.35
I discovered that copying the folder out of the deep directory structure and placing it directly in C:\ (the root directory) resolves the issue. The problem was (apparently?) caused by the excessive path length.

The original path had >130 characters and followed a deeply nested structure

viv · January 14, 2026, 7:32pm

I already purged the whole configs folder, so can’t really test it.
