Broken UI on GNOME in Debian Trixie with AMD graphics

[nykula]

Hello! On a fresh Debian Testing install with GNOME, on top of AMD integrated graphics, after terminatorX loads a sound, the audio scroll widget disappears along with the menu, and the program crashes after a while. This happens in both Wayland and X11 sessions. When I launch terminatorX in terminal, the latter is flooded with such warnings when the issue happens:

(terminatorX:281565): Gdk-CRITICAL **: 13:53:24.142: gdk_x11_window_get_xid: assertion 'GDK_IS_X11_WINDOW (window)' failed
play WARN alsa: can't encode 0-bit Unknown or not applicable

(terminatorX:281565): Gtk-WARNING **: 13:53:30.725: drawing failure for widget 'GtkTx': NULL pointer

(terminatorX:281565): Gtk-WARNING **: 13:53:30.725: drawing failure for widget 'GtkWindow': NULL pointer

Here is the video card model, I haven't installed any custom drivers, only what Debian provides out of the box:

04:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Renoir [Radeon Vega Series / Radeon Vega Mobile Series] (rev c4)

I understand that by using Testing instead of Stable I'm likely to get bugs, but this means that there has appeared an incompatibility of terminatorX with recent versions of GTK or something, so please try debugging this when you have time, while these versions haven't made their way to Stable yet.

Thanks for your report, I do get the GTK+ error messages, albeit no crashing so far. Unfortunately even running with a debug-enabled GTK+ didn't help to identify the root cause yet. Hope to find some time to give it another shot soon.

Here are the steps I found that sometimes reproduce the crash. Launch terminatorX, connect MIDI control input using Helvum, tap MIDI button in terminatorX, move two-axis joystick along X axis, tap Bind (to Speed), tap Close, load audio file, tap Power, start rotating joystick.

It doesn't always crash, many times it just says to terminal:

(terminatorX:37540): Gtk-CRITICAL **: 01:03:33.141: gtk_label_set_text: assertion 'GTK_IS_LABEL (label)' failed

Or replaces the text of a random widget, such as a table column header or a button, with the Type/Number/Channel info.
