[Bug] Stop button state persists after generation & Window flickers when dragging

System details / 系统信息

AMD Ryzen 7840HS,Windows 11,Deepchat 0.5.5

What's wrong? / 出了什么问题？

I have encountered two issues while using the application.

1. Stop button does not revert to Send button after generation completes
   After the LLM (e.g., GPT-5.2) finishes generating the response, the "Stop" button (red square) in the bottom right corner does not automatically change back to the "Send" button (arrow icon). I have to manually click the Stop button once to reset the state before I can input a new message.
2. Window flickers/jitters when dragging
   When I drag the application window with the mouse, the window flickers or flashes significantly. specifically, when I drag the window to the right, the window frame seems to flash frequently on the left side instantly.

Steps to Reproduce
Issue 1 (Button State):
Send a query to the LLM.
Wait for the generation to finish completely.
Observe the bottom right action button.
Result: It remains as a "Stop" button instead of switching to "Send".

Issue 2 (Window Dragging):
Grab the title bar/header of the application.
Drag the window quickly or normally towards the right side of the screen.
Result: The window flickers visually on the left side during the movement.

Thank you for the detailed report and clear reproduction steps. We have a few suggestions and preliminary observations regarding the issues you described:

Issue 1: “Stop” button does not revert to “Send” after generation completes

Please check the assistant model settings in the application.
We recommend switching to a faster model that does not include a reasoning/thinking phase and testing again. This issue may be related to the timing of the generation completion callback for certain models.

Additionally, please enable logging in the settings, reproduce the issue once more following your steps, and submit the generated logs to us. This will help us investigate why the button state is not being reset correctly.

Issue 2: Window flickering/jittering when dragging on Windows

Regarding the window flickering when dragging (especially the flashing on the left side), this appears to be an Electron compatibility issue on Windows.

In our local testing, the issue no longer occurs after upgrading the Electron version. We recommend observing this behavior again in the next release, which includes the Electron upgrade.

Thank you again for your feedback. It’s very helpful for improving the application.
If you encounter any issues while switching models or collecting logs, please feel free to reach out.
