Wing Pro 9 freezes when debugging pygame-ce project

I'm using Wing Pro 9.1.1.4 in Ubuntu 22.04.

My project uses pygame-ce (ce is community edition) with Python 3.10.12

When I put a breakpoint to debug my pygame project, Wing IDE freezes and then I must use htop to terminate the process and then restart Wing.

Wing will also freeze sometimes when my code raises an exception. I haven't had this issue with other libraries such as tkinter; I think this issue is specific to pygame. Any ideas?

I suspect something is going wrong with inspecting data in your code in order to display it in Wing's Stack Data or other debugger tools. Could you please send in a bug report from the Help menu after replicating the problem? That might show us what is failing. You could also try to set the Debugger > Diagnostics > Debug Internals Log File preference and sending us that output (but without the extremely verbose option).

Based on emailed details, this is probably an XGrabPointer or similar locking up the entire Linux UI and not being released when a break point or exception is reached. There are some possible solutions listed here: https://wingware.com/doc/debug/debug-x-…

Thanks, I plan on switching to Debian 12 soon (which I believe uses Wayland), so that might be a solution for me (apparently the MATE desktop, which is what I use, doesn't support Wayland).

In the short-term you may also just be able to move where you put a break point, or rework code a little. In Wing, we had this a lot for code that was actually doing a menu item's action during the menu selection time, when the XGrab was still in place. By instead scheduling an action that happens after the UI menu action is completed (and XGrab is released) the problem largely went away. This may or may not be useful, though, depending on your code.
