I am developing a Python/Tk application on a Raspberry Pi (ver.4 Model B Rev 1.2).
Its OS is 5.4.83-1-MANJARO-ARM #1 SMP PREEMPT Mon Dec 14 08:37:33 CST 2020 aarch64 GNU/Linux, the software versions are python 3.9.1 and tkinter version tk 8.6.12-1
I don’t know what I’m doing wrong, but any tkinter.filedialog.askopenfilename call shows just the files icons, and invisible filenames. Just selecting a filename it becomes (and stays) visible.
(sorry, as a new user I cannot post screenshots)
I’ve been suggested that this could be a Manjaro/KDE issue, not Tkinter, so I wanted to ask you if it ever happened to you.
