Chooser.files.native still broken

PerryJohnson · September 19, 2026, 8:18pm

I’m still seeing a broken file chooser on the latest Processing versions up through the latest RC. I’m on Linux (Fedora, KDE, Wayland).

Yes, there is the preferences workaround below, but I was hoping for a proper fix. Any progress on this? Thanks to the dev team!

Hi @PerryJohnson,

Are those issues related with what you are experiencing?

bug help wanted

### 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...) <img width="845" height="604" alt="Image" src="https://github.com/user-attachments/assets/4e93439b-b946-4116-a074-2cc52c5985a8" /> ### 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

launcher setting ignored in preferences.txt

In GitLab by @hamoid on Aug 12, 2021, 09:08 ## Description Executing "Open S…ketch Folder" on Arch Linux with i3wm and fish does not open the folder. I used to work around this by specifying a custom `launcher` setting. This worked in Processing 3.4, but not in later versions. This affects very few people I guess (maybe 1?) but it would be nice if the launcher setting was enforced if present, as an override. The related lines are found here: https://github.com/processing/processing4/blob/master/app/src/processing/app/platform/LinuxPlatform.java#L118 ## Expected Behavior I can use Open Sketch Folder ## Current Behavior I can't use Open Sketch Folder. It opens a terminal window with text being printed forever in a loop. ## Steps to Reproduce Press Ctrl+K ## Your Environment * Processing version: 4.0b * Operating System and OS version: up to date Arch Linux * Other information: using i3 window manager ## Possible Causes / Solutions I think a solution might be to tweak the order of the if statements: if a launcher is specified, use it, otherwise, try use the default approaches. But I don't know how messy touching any of that might be. Old post about this issue: https://discourse.processing.org/t/launcher-seems-to-be-ignored-in-the-preferences/10840/7

Yes, I believe it’s the same issue as the first - Open/Save File browser panels blank on XFCE Linux.
