   It thinks the terminal supports explicit width for some reason. These are explicit width sequences. The capability detection seems to be off here. I'll check that.

   Is there a solution to this problem? I am currently experiencing this issue in the latest version as well.

   Install a different terminal, such as Konsole

   This is still an issue for me as well (GNOME Terminal v3.28.3 on RHEL8) with the latest opencode version (1.1.21) forcing me to use the old v0.15.31.

   Can you get an opentui-examples release from https://github.com/anomalyco/opentui/releases/tag/v0.1.72 for you platform and run the "Keypress Debug Tool" and show me the capabilities it shows? shift+s should also write that out as json in the cwd.

    Is this what you're looking for?

    Yes. Curious. It says it supports explicit width, but doesn't handle the escape sequences properly. I am getting a setup up to debug this properly.

    Oh I just remembered, in the meantime you can try setting OPENTUI_FORCE_EXPLICIT_WIDTH=0, which might fix that.

    I tried that option and nothing seems to have changed. In case this is relevant: I've had similar characters in vim that were solved by setting set t_RK= t_TE=. Here is the issue that helped me solve it: vim/vim#11728.

    Running gnome-terminal --version returns # GNOME Terminal 3.28.3 using VTE 0.52.4 +GNUTLS.

    I cannot reproduce that with GNOME 3.28 on ubuntu. Where the heck do I get an RHEL8 image? Have you tried upgrading the GNOME terminal or using one that is officially supported by opencode?

    It's a work computer that runs RockyLinux 8.10. To test it you can download a bare-bones image on their official website: https://download.rockylinux.org/pub/rocky/8/isos/x86_64/Rocky-8.10-x86_64-minimal.iso. I have no root access so it's hard to install other terminals like konsole, but we do have terminator installed and it has the same problem as GNOME terminal. It looks to be a deeper problem than just switching emulators. That said, I talked to our sysadmin and we are due for an upgrade to RHEL9 in the upcoming weeks. Would be nice to get a working version until then but if it's unfeasible I'll just wait.

    terminator can not work for me, too. But I found that this issue does not occur in the terminal of VSCode, even without the OpenCode plugin installed. I am currently using opencode in this way.
