Grok Bot Windows — window freezes (goes black, "Not responding") when opening any chat with images; mobile works

Where does the bug appear (feature/product)?

Grok Bot

Describe the Bug

The app starts normally: for 2–3 seconds the full UI is visible (bot list, chat loading, “Computer is sleeping” panel). As soon as a chat that contains images starts rendering, the window turns black and stops responding. It never recovers — only killing the process helps.
Chats without images open fine. The same account and the same chats work normally on my phone.

Steps to Reproduce

  1. Launch Grok Bot on Windows.
  2. Open (or have last-opened) any bot chat that contains images.
  3. Within a few seconds the window goes black / “Not responding”.

Expected Behavior

Chats with images should render normally, as on mobile.

Operating System

Windows 10/11

Version Information

0.78.1

For AI issues: which model did you use?

What I already tried

  • Launched with --disable-gpu — no change
  • Cleared local data (renamed %APPDATA%\Grok Bot) and signed in again — no change
  • Deleted the bot whose chat triggered it first — now any other chat with images freezes the same way
  • VPN on/off — no change
  • Windows Event Viewer has no crash/hang entries for Grok Bot
  • ~/.grokbot/local-exec-daemon.log shows normal connections (connected in ~200–700 ms, no errors today)

Additional Information

Report file with logs attached. The local computer and the hosted computer connect fine; the problem seems to be only in rendering images in the desktop window.

Does this stop you from using Cursor

Sometimes - I can sometimes use Cursor

Hey @Veronika!
This one’s on our side, not your setup, which is why clearing data, disabling the GPU, and the VPN toggle didn’t change anything, and why mobile is fine. A fix just went out in 0.78.3 (released today). Grab the latest Windows build from ! https://x.ai/bot and image chats should render normally again. If it still freezes after updating, reply here and I’ll take another look. @globe_Show, same fix applies to you.
