No names/ports in Nodes after locking and unlocking screen.

[stijn-vanesch]

Describe the bug
When locking and unlocking the screen with an open tree in the editor, the nodes lose their names and input ports as visual information.

To Reproduce

1. Open a behavior tree in Groot2 in the Behavior Tree Editor.
2. Lock the screen.
3. Unlock the screen.
4. Visualization is not present anymore.

Note: this behavior seems to be flaky, it does not happen every time, but noticeably often.

Expected behavior
The BT nodes should not lose their visual information when locking/unlocking a the screen.

I tried to reproduce the issue but had no luck. I tested on Ubuntu 24.04 in VirtualBox and Ubuntu 25.04 in WSL on Windows 11. In each case, I repeated the lock and unlock sequence 15 times.

My assumption is that the issue might be related to the installed video driver. I'd suggest collecting system logs once the problem is reproduced (journalctl -b, dmesg, /var/log/Xorg.0.log) and inspecting them. Is it possible to attach the mentioned logs right after the issue is reproduced?

I am having this issue as well, i could not find anything interesting or useful in those logs, we have only started noticing it since 1.8.0.
