Mouse-over causes IDE to freeze/lock up

[ulrichsorensen]

Description
When using mouse over to show content of variables or functions etc. the IDE will typically freeze after a couple of seconds showing the mouse over window. The window content is correctly shown and the window can be closed with the ESC key, but Eclipse is frozen afterwards (unresponsive to key presses or mouse clicks) and the only way to terminate Eclipse is to kill it.

To Reproduce
Steps to reproduce the behavior:

1. Move mouse over variable or function to see content
2. IDE freezes

Expected behavior
After the mouse-over window has been shown, the IDE was expected to respond to normal user inputs through keyboard or mouse.

Screenshots
None

Could be something specific to how swt works, I seldom encounter similar behavior over remote X11 session. No idea how to dig deeper but could be worth asking at swt https://github.com/eclipse-platform/eclipse.platform.swt/issues

[ulrichsorensen]

Thanks for pointing me in that direction. I looked at some of the SWT issues and other people report issues that could be related or similar.
I tried a couple of the suggested solutions changing the environment variables but none fixed my issues.

Any other suggestions to try will be appreciated.

If you get this again, can you run jstack so that we can see what the main thread is doing that is preventing updates?

@ulrichsorensen everything looks idle in the jstack output.

The window content is correctly shown and the window can be closed with the ESC key, but Eclipse is frozen afterwards (unresponsive to key presses or mouse clicks) and the only way to terminate Eclipse is to kill it.

I am not sure how to proceed on this one - if you have it reliably reproducing there are some things to try:

1. start Eclipse with GDK_BACKEND=x11 and GDK_BACKEND=wayland and report if you see the problem in only one of them.
2. provide me some additional details on your setup, in particular GTK versions. Help -> About -> Installation Details -> Configuration -> type swt.internal, like so:

3. Let me know anything else that may be unusual about your setup.

[ulrichsorensen]

Hi Jonah,

Thanks for getting back to me regarding my problems.

I recently upgraded to Eclipse Version: 2025-12 RC1 (4.38.0 RC1) and I have not seen any errors since.

If the error returns, I will try the things you suggested and report back.

/BR
Ulrich

Thanks @ulrichsorensen for reporting back. I am relieved to hear you aren't hitting the problem anymore, I will 🤞 that someone specifically fixed a bug in the Eclipse Platform and that you are now benefiting from that.

Please do let me know if you see this problem in the future.
