When I paste a lot of content into the input box, it appears as shown in the image—nice and tidy.

But after pressing Enter and continuing the conversation, this large amount of content renders poorly—it looks visually messy, the text even overflows the chat box, and the copied text blends in with the question, making it hard for me to review the previous dialogue.

This issue might be a duplicate of existing issues. Please check:

  • #372: The chat history gets covered up if the chat box is getting too big
  • #642: Text input overlays the chat/messages
  • #1098: Copy pasting a large text makes it impossible to scroll it to the end
  • #1526: Pasting something big causes UI issues
  • #2582: Prompt box overflows on top of LLM response and cannot be shown with scrolling (closed)

Feel free to ignore if none of these address your specific case.

Gotcha, I think we may have this fixed in our opentui version

Generally we recommend:

A modern terminal emulator like:
WezTerm, cross-platform
Alacritty, cross-platform
Ghostty, Linux and macOS
Kitty, Linux and macOS

But i hope we can get the tui rendering inside vscode decently too

I mainly use it in WSL on Windows; VS Code lets me develop inside the Linux environment effortlessly. The screenshot above was taken there.

By the way, the situation is just as awful in PowerShell.

I have another problem with pasting - when I paste something in opencode with "ctrl + shift + v" it's being pasted letter by letter, as if somebody is typing it very fast. If I paste something big it will write for a long time and I can't cancel the pasting or exit terminal with ctrl + c. But when I try pasting to terminal outside of opencode with "ctrl + shift + v", it pastes instantaneously, unlike in opencode.

Have the same issue with Xfce terminal that use VTE (similar to Shift+ENTER).

If you think that SHIFT+ENTER and this is the problem with VTE, feel free to report a bug. You may get (as I did) explanation and help if this is not a bug in VTE, but in OpenCode. But if this is VTE issue it may fix more terminals.
