Huh, your title scared me, because I was hunting down crashes in the TSM resize layer for like 2 weeks and thought they are finally fixed. But it's only a freeze, that's ok. I guess it's because of a missed frame-callback.
Could you describe the problem a bit more detailed? I'm especially interested in the "./wlterm --debug" log. Also, what do you mean by "closing"? Do you kill the binary or does the "exit" button still work? Does the whole app freeze or does only the keyboard input freeze? Does resize still work? Can you still move the window? What Wayland version are you using? Are you running it under weston? Please note that I am currently working on getting kmscon-6 out, so I haven't spent too much time on wlterm. In fact, I didn't update it correctly to the Wayland-1.0 API. I hope I can rewrite that layer at the coming weekend, but no guarantees, sorry. Any patches are welcome.
To debug this, can you run wlterm with --debug and then send a signal to wlterm when it freezes? (something like SIGUSR which doesn't kill wlterm). And if you are comfortable with GDB, can you attach GDB to the freezed process, send SIGTRAP to it and print a stacktrace?
Thanks for the report! Maybe this will get fixed with my rewrite automatically. David
Sorry for the very moderate bug description.
After trying to resize the window I just can't enter any text or resize the window any more. But I can still move the window and closing the window through the exit button on the title bar also still works.
Here is the backtrace after sending SIGTRAP when wlterm freezing. Just let me know if you need more output. Sending SIGUSER just quits wlterm without producing a different output.
Currently logging to "wlterm.log".
Logs will be appended to the log file.
Output is being logged and displayed.

Yeah, that sounds like some missing frame-event. Sorry for the delay, but I am currently swamped with other work. The WLT rewrite is still on my todo-list and I will try investigating more tomorrow.
Thanks a lot for the report! David
I got a fix for that: e0f798071c786e4b2e622d18d1cd1ab0dba585ae Can you test whether this fixes the problems?
Sorry for the delay, but I was working hard to get kmscon ready for FOSDEM13. I will try to rework the WLT toolkit in February. David
Yes this fixes my problems. Thank you.
Sometimes when I try to resize the terminal window it freezes and I can't enter anything except for closing the window.
