Element (Advanced Sequencer) is freezing after start

When I run Element sequencer (installed from the pro-audio group), it immediately freezes with the following error:

$ element
The program 'element' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadDrawable (invalid Pixmap or Window parameter)'.
  (Details: serial 274 error_code 9 request_code 55 minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

An "strace" on it shows me the following "Timeout" error in a "endless" loop:

futex(0x556b883cac08, FUTEX_WAKE_PRIVATE, 2147483647) = 1
futex(0x556b883cac10, FUTEX_UNLOCK_PI_PRIVATE) = 0
futex(0x7fc36c91ce60, FUTEX_UNLOCK_PI_PRIVATE) = 0
poll([{fd=4, events=POLLIN}, {fd=8, events=POLLIN}], 2, 0) = 0 (Timeout)
poll([{fd=4, events=POLLIN}, {fd=8, events=POLLIN}], 2, 2000) = 1 ([{fd=4, revents=POLLIN}])
poll([{fd=4, events=POLLIN}, {fd=8, events=POLLIN}], 2, 0) = 1 ([{fd=4, revents=POLLIN}])
read(4, "\377", 1)     

Package info:

$ pacman -Qi element
Name            : element
Version         : 0.44.0-2

If I run it with the "--sync" parameter it doesn't freezes, but this option is used for debugging, not for daily usage.

Is anyone else facing the same issue?

Thanks

Re: Element (Advanced Sequencer) is freezing after start

BTW, Element package has just been upgraded, but I didn't tried it before the upgrade.
