Event sheet becomes less responsive after running for a few hours

[tristanbob]

Describe the bug

After using GDevelop for several hours:

• We lose the ability to edit fields directly from event sheet (opening the condition/action editor still works)
• Conditions/Actions seem to highlight and not let go
• Closing and opening GDevelop fixes the problem (until it happens again)

GDevelop in Task Manager (6 processes)

Other details

• Windows 11
• GDevelop 5.0.136

@tristanbob Do you have the same problem with version 5.0.137 ?

[Silver-Streak]

@Bouh I have confirmed the items Tristan is reporting above all still happen for me in 5.0.137.

When this is happening, is closing the events editors/all scenes and opening them again enough, or is the whole app still sluggish? Is it the whole app or just the events editor?

[VanCastar]

This bug needs a full restart of GDevelop. It's been around forever, atleast a year or so.

Here's how to reproduce it instantly.

This is the same issue as in here that I mishaply started. https://github.com/4ian/GDevelop/issues/4473

FYI, We fixed many memory leaks in the app on September 23rd (via https://github.com/4ian/GDevelop/pull/4323) including one that was happening for each condition/action on the events sheet. I'm not saying this should have fixed the whole user experience on the events sheet, but it should be a good start.

Thanks @VanCastar, this really helps narrow down what is causing it.

Step to reproduce (from video)

• Click on an action to open the mini-popup editor
• While that mini-popup is still open, drag that action to another event
• The problem state is triggered; no more mini-popups can be used until GDevelop restarts
