Open/Save File browser panels blank on XFCE Linux

Most appropriate sub-area of Processing 4?

PDE

Processing version

4.4.7

Operating system

Manjaro XFCE Linux

Bug description

When you do a file operation like Open or Save, the window of the "OS File browser" is blank.

Steps to reproduce this

1. Install Processing using sudo snap install processing --classic as recommended at Processing.org

2. Launch the PDE

3. Try on the File menu > Open... (or Save...)

Additional context

This was working on Processing 4.3.3 on the same machine. I saw it on 4.4.6 and tried to uninstall and upgrade to 4.4.7 but it is still the same.

Would you like to work on the issue?

No, I’m just reporting the issue
