What version of the Codex App are you using (From “About Codex” dialog)?

Version 260205.1301 (554)

What subscription do you have?

Plus

What issue are you seeing?

the app window drawing is shaking/glitching during some activity.
Specifically I have observed it while

  • Codex active work in thread + user digging through diff tree to leave comments in parallel to it
  • Codex constructing mermaid diagrams, window trying to re-render it with every new mermaid syntax line and whole App picture on the screen get broken until action completed

What steps can reproduce the bug?

  1. Run some long process tasting and try to browse through file diffs, pick and change ant leave comment
  2. run request to generate some big enough mermaid diagram and you see how mermaid rendering and codex generated mermaid script view are conflicting each other, overlapping and creating a mess.

What is the expected behavior?

Should be smooth with no shaking and image breaking
