What is going on with the layout of my PhpStorm?
I've skipped the last couple of PhpStorm updates because there's always something that breaks, but I recently had to update to 2026.2.3 and now my editor panels are all over the place! Panels that are meant to be pinned to the sides just expand to fill the screen if I close the main editor windows. The way the layout reorganises itself makes absolutely no sense. That never used to happen until this update.
Can anyone tell me how I disable whatever this annoying new behaviour is?

Please try resetting/saving the layout via Windows | Layouts | ...
If that doesn't help though, please share a screencast demonstrating the behavior.
You can upload it here: https://uploads.jetbrains.com and share the upload ID so I'll review that.
Thank you for responding. I've tried saving/reloading the layout and going back to default, but that's made no difference.
I'll try to describe the problem more clearly now I've had more time to understand what's going on.
2026_10_25_83D511mgMT77K46nMPNA2E Shows how I have my layout set up. I have the project structure to the left, and the AI chat (Air) panels to the left. Along the bottom is my terminal. All looking fine.
2026_10_25_2AZaHG3W8WbWDpwo3u57Bf shows what happens when I close all editor windows though. The right-hand AI panels stretch across the screen and the terminal is stretched top-to-bottom, but squashed between the project view and AI panels.
Prior to installing this version, the layout remained as it was set up, with the empty editor space left blank and the tool panels staying in place at the sides.
For some additional context, if I disable Air and go back to using the AI Assistant tool window, I have the stable layout as was in the previous PhpStorm version. So, I guess this is just a problem with running Air in a tool window.

Does it help if you disable Agentic Layout? To disable run Shift+Shift > type "Agentic Layout" > Enter. If issue persists can you please collect a set of logs via Help | Collect Logs and Diagnostic Data, upload them to our secure server (https://uploads.jetbrains.com/) and share the ID? This will provide us a bit more context on the setup you are running. Thank you!

When I hit shift-shift and type “agentic layout” there's nothing found… Unless I'm doing something wrong?
The log entries that appeared after I closed the only open editor (brief.md) were these…

```
When I did this, the Air tool panel filled the screen and my git tool panel that was along the bottom of the layout was squished between the project view and Air panel.
This only seems to be an issue when Air is enabled and I have the Agent Sessions or Air Chat open. Other tool windows, such as Notifications and AI Assistant behave normally. I have also uploaded a screencast to demo the issue

Thanks for the additional information! This narrowed it down to a known issue: https://youtrack.jetbrains.com/issue/IJAI-5074.
We do have a workaround:
Hide the Air Chat tool window while you have no file open. The empty editor area and the Terminal's height come back. Showing Chat again with no file re-triggers it.
Please let me know if that helps!

Thank you for the info. I will keep an eye on that YouTrack issue.
Kind regards,
