Screen becomes completely blank
Description
Not sure when it happens, but I'm in a session and many times the screen becomes completely blank:
When I trigger a switch theme, I get the contents back.
I noticed it while working inside VS Code. Switching to Ghostty to see if that was the cause, but I have the same issue there.
OpenCode version
1.0.12
Steps to reproduce
No response
Screenshot and/or share link
No response
Operating System
Mac
Terminal
Ghostty, VS Code terminal
This issue might be a duplicate of existing issues. Please check:
- #3719: navigating away from an active session causes it to flicker/be blank when returning to it
- #3697: OpenTUI: Missing main view text when resizing
- #3541: The screen is bugging out with the new "Screen"? - reports screen display bugs and blank areas
- #3671: 1.0+ is unusable in non-truecolor terminal - display issues causing blank/unusable interface
Feel free to ignore if none of these address your specific case.

It looks similar to https://github.com/sst/opencode/issues/3697, but I don't need to resize my screen to trigger it.
I see this often as well. Any time I start start opencode and select a previous session, the TUI is blank. Any time there's a long running process, the TUI also becomes blank, but eventually fixes itself.
Ive fast fixed this in linked PR, half of my sessions are blank :-) cc @rekram1-node
I see this constantly when working with multiple concurrent opencode instances in Zellij tabs. Makes it kinda hard to work :)
Still happens to me on 1.0.23. :(
I found a workaround: Ctrl+P then Jump to message, or just Ctrl+X G.
This happened when I resized the window.
Yes, to me to. Selecting switch theme also brings it back.
After working a bit more, I see that switching to subagents also causes the screen to go blank in many cases.
Yeah, for me it always go blank after large output produced by a subagent.
Two things I've noticed:
- If you switch to the subagent while it is still working, when you are back the screen is blank. However if you wait long enough, any updates on the subagent operations will become visible, yet the old information is not.
- If you keep going up in the message history eventually you reach a point that it starts showing you messages. Then you can scroll all the way back and everything is back to normal again
Besides what's observed here, I've noticed that the UI sometimes freezes.
What I noticed then was that the fetch tool failed in the subagent, and then it froze. When I closed that instance and restarted the session from another Opencode instance, I could see the subagent's errors, which were not visible in the original instance.
Not extensively tested yet, but it either doesn't happen anymore or occurs less frequently. I will provide an update after using it more.
Gave up and downgraded to 0.15 today. it still happened so much it was unusable at .35 today (along with ctrl u not working and /commands not working correctly just to much to keep trying)
Havent seen screen issues, but it hangs now for like half a minute on session switch.
Happens for me still every time when I maximize the window on maocs (full screen) and then make it window again in yabai. (Also happens when I resize from bigger to smaller). Sometimes scrolling helps but sometimes not.
I have it on 1.0.35
@istarkov after it hangs and loads can you do control+p and toggle the console and send a screenshot of it
I know I'm not Ivan but still.
Do I have to enable something more?
that's how it looks like when I enable debug window.
On small 5s freezes I see fetched, synced 5k+.
But on huge freeze like 2 minutes, here is what I see.
Keyboard is not working at all, I can't switch to log or do anything.
All number is the log are ok, message updates etc like every fews second.
Rendering - code parts, can be rendered much more later vs everything else.
Sometimes I see something like this in the terminal after ctrl-c exit
M65;43;7M65;43;7M65;43;7M65;43;7M65;43;7M65;43;7M65;43;7M65;43;7M65;43;7M65;
I have 672 session files at /Users/ice/.local/share/opencode/storage/session/f143c64c3403d3d44a56c2c5a6c1ffa3b70d2f06 Gonna delete all to see if it works.
PPS: It freezes with 11 session files too
PPPPS:
When I see this in log, it's ok it's slow but not freezed
Even after removing code blocks in dev, it still freezes (so it’s not the highlighter). I’ve tried the Bun debugger, but it doesn’t pause when the freeze happens (pausing in debug usually helps find the hot path).
For me it certainly happens less often, and it seems to recover better than before, but still, I sometimes see blank screens.
