UI Freezes When Focusing on Textbox on Linux

[zicklag]

Hey there, thank you for a nice tool!

Unfortunately I'm having a problem where whenever I focus on the textbox in the chat tab, it freezes the UI. Interestingly, the UI is actually still working, it's just not re-rendering. It only re-renders after I resize the window. So I can type into the box, and not see anything happening, then I resize the window, and I can see what I typed. It's the same for buttons and every other UI interaction.

I'm using the v1.7.5 release on Pop!_OS ( Ubuntu ) 22.04.

Go to the Configs page, check Enable WebUI and run the model, then open http://127.0.0.1:8000 in your browser. Does the issue still exist at this point?

The web UI works completely fine.

Actually, the code of client and webui is exactly the same. The difference is that the client uses the system webview rendering. Therefore, I believe this may be an issue with the system's webview. At least, I haven't encountered this problem on Windows, macOS, or Ubuntu.

Perhaps you can try compiling from the source code. The Linux client in the releases was compiled on Ubuntu.

My system should be very similar to Unbutu. What version of Ubuntu are you using?

I may have to try to compile it myself and run in debug mode to see if there's anything suspicious in the logs or web inspector.

Unfortunately Webkit is notorious for having all kinds of bugs and messing things up for things like Tauri, etc. I've done a bit of messing with it before, just not with wails and go.

I suggest you use the webui for interaction, which has no difference in functionality compared to the client

I suddenly remembered a potential issue: when the client enables webui, it will simultaneously enable deployment mode. Under Linux system, rwkv-runner server starts as a subprocess of the client. And in deployment mode, you cannot terminate the process through the client, so every time you switch models, you have to restart the client.

What version of Ubuntu are you using?

Ubuntu 20.04

That could be fine, but I was hoping to be able to use the WebGPU ( non-Python ) backend if possible, which doesn't have the option to host the WebUI.

Ubuntu 20.04

Ah, maybe that's the issue, since my distro is newer at 22.04.

I'll try running CI on a fork with a newer Ubuntu version and see if that helps.

Unfortunately that didn't fix it. I'll have to try building from source locally.
