Arduino UI Broken and Unuseable


As shown, the menu is stuck underneath the window buttons making it unuseable. I am on windows 11.

It's a known issue that at occasion occurs; I think that this was the first report: A setting has changed.

Close the IDE (e.g. <ALT><F4>) or kill the IDE using the operating system tools).

After one or two restarts of the IDE it comes right again.

The Arduino IDE developers are tracking the bug of Arduino IDE randomly switching to the non-functional "custom" title bar style here:

I was one of the people that reported this problem months ago. Several fixes were offered but most of those did not work. Finally, one user suggested that when I open the IDE, only have ONE sketch open. So now when I am done for the session, I close all but my latest sketch and on the next start up, all seems to be fine. Hopefully it stays that way until the real issue can be found and fixed !!

Is there a final fix for this yet.
I get this issue when I have several sketches and their serial monitors open at the same time. Say when tracking info going from a number of sensor RF24 nodes to a master RF24 node which then manages sending the data to an ESP32 with SD card storage prior to the ESP32 making historic information available over a Web Server and / or BLE. When the issue occurs I have to close everything and start again possibly more than once. This renders the Arduino 2 environment NOT FIT FOR PURPOSE. The solution given as being just restart everything is not a solution. If no fix then I will bin it and go back to the Arduino 1 environment and open multiple instances to monitor data flow as mentioned above.

It does not look like it. Nobody assigned to the github issue yet.

Restart the IDE.
