Minimal Ghostty Configuration

custom-shader = shaders/cursor_smear.glsl

Additional Relevant Configuration

No response

I acknowledge that:

• I have reviewed the FAQ and confirm that my issue is NOT among them.
• I have searched the Ghostty repository (both open and closed Discussions and Issues) and confirm this is not a duplicate of an existing issue or discussion.
• I have checked the "Preview" tab on all text fields to ensure that everything looks right, and have wrapped all configuration and code in code blocks with a group of three backticks (```) on separate lines.

cant reproduce on 6590196661f769dd8f2b3e85d6c98262c4ec5b3b adding the first cursor shaderI found online https://github.com/Linear-optimize/dotfiles/blob/master/ghostty/shaders/cursor_smear.glsl works in multiple tabs

I tested both Debug and ReleaseFast builds

[ReStranger]

Apparently the configuration wasn't fully applied; after a restart, the error doesn't play

[rhodes-b]

you never noted an error in the original?
I still can't reproduce the problem in either scenario first starting up ghostty with custom-shader set
or with reloading the config at runtime to add the shader it worked fine in both cases

[ReStranger]

Don't waste your time, I can't reproduce this bug either :D
