Grey/White bar on right side of sketches in Processing 4.3 on Manjaro w/ KDE Plasma 6, Wayland

[peterambos]

This is my first time writing an issue on a software project, so if I'm doing anything wrong, please let me know. I've searched for this issue on Google, here and the forums and found nothing so far, and read the guidelines for submitting issues and the troubleshooting page, but if I'm still doing something wrong, please tell me.

Description

When running a sketch in Processing 4.3, there always is a grey/white bar on the right side of the output, despite it not being coded to be there. The bug persists after uninstalling and reinstalling.

Expected Behavior

The sketches running without a unwanted bar appearing on the right side of the output.

Current Behavior

See Description.
Example Screenshot:

Steps to Reproduce

1. Open Processing 4.3.
2. This is the smallest amount of code I found to be able to reproduce the bug:
   void setup() { size(400, 400); background(0); }
3. Run the Sketch, which produces the output given in the screenshot given above.

Your Environment

• Processing version: 4.3 (64 Bit)
• Operating System and OS version: Manjaro Linux 6.10.13 w/ KDE Plasma 6.1.5 on Wayland
• Other information: I've attached a txt with my inxi output for further information.

I'm happy to provide any further information if needed.

Hi, quick question, do you use a scaled UI mode on your display, e.g. 125% on 2560x1440

[peterambos]

Jup, I use a scale of 120 % on a 2560x1600 display.

[Stefterv]

Okay, could you test for me turning it to 100% scale for a second, I suspect the issue is with having non-integer scaling

[peterambos]

Sure! The bar is unfortunately still there after turning the scale back to 100%. Even tried logging out and back in to start a new session after changing the scaling, but the bar is still there.

[Stefterv]

Okay, thank you so much for trying, will need to be looked into deeper with a vm of your OS then

[peterambos]

Got it, if you need any more information, just let me know.

[peterambos]

Since there was an update, just wanted to report this issue still persists in Processing 4.3.2 on the 2025-01-18 testing branch update of Manjaro with Plasma 6.2.5.

Thanks for the ping, I just set up a vm and I'm seeing the same thing:

Switching to P2D solves the issue

Hi @PeteAmbos I've created a pull request with a potential fix, could you please try the test build created here and let me know if that solves your issue
