 This is some bizarre interaction between some locales (specifically, LC_NUMERIC)
 and GTK4. You can see the same issue with gtk4-demo:
 
 $ LANG=es_ES.UTF-8 gtk4-demo
 
 GTK3 (gtk3-demo) looks fine. So does using a US, UK or JP locale:
 
 $ LANG=ja_JP.UTF-8 gtk4-demo			# works fine too, but not fr_FR!
 
 However, only LC_NUMERIC seems to be the culprit (don't ask me why or how), so
 you can do this as a workaround to keep the language:
 
 $ LANG=es_ES.UTF-8 LC_NUMERIC=C pavucontrol	# or gtk4-demo
