Copilot Chat Code Blocks Collapse / Disappear During Scroll

[dmiska25]

Does this issue occur when all extensions are disabled?: Yes besides copilot chat

• VS Code Version: 1.105.0 (OSS Build)
• OS Version: Mac OS

This is an issue that occurs when a conversation has a lot of code blocks(>100). While scrolling through the conversation the code blocks will shrink and become invisible.

Steps to Reproduce:

1. Load(or create) a copilot chat conversation with >100 code blocks
2. Scroll up and down the conversation(top to bottom and bottom to top a few times)

Example:
