Is there a workaround for the Unity “maximized window” bug in versions prior to 2023 without upgrading?

I’ve been wrestling with this annoying “maximized window” bug in Unity again, especially since I’m using a version prior to 2023. For those of you who haven’t run into it, the issue is that when I set my project to “maximized window,” it throws the game into full screen mode instead, which is not what I want at all. It’s so frustrating because I have a specific layout and workflow that relies on a windowed view.

Honestly, upgrading to 2023 would fix this, but I really don’t want to go through the hassle of updating everything. You know how it is—sometimes upgrading can introduce a whole new set of bugs or require you to refactor your code for compatibility. I’d rather find a workaround that lets me stick with my current setup.

I’ve tried checking the Unity forums and there are a few workarounds suggested, like manually adjusting the window size in the code or playing with the display settings in the Unity editor, but they haven’t worked so far for me. I was wondering if anyone here has faced this issue and if you’ve found any lines of code that you can drop into your project to manage the window behavior differently.

Maybe there’s a script or a configuration file I can tweak? Any hidden settings I should know about that might help override this bug? I can’t be the only one stuck dealing with this, so if you’ve found a hack or a solution that actually works, I’d love to hear all about it. Bonus points if it’s something I can implement without diving too deep into Unity’s internals. Thanks in advance for any help! I really want to get my project back on track without having to make the jump to a new version.

    1. Oh man, I totally get your frustration with that “maximized window” bug in Unity! Dealing with versions that aren’t the latest can be a pain, especially when things just don’t behave as expected.

      Since upgrading to 2023 feels like a hassle, let’s explore some potential workarounds that might ease your pain:

      • Update Player Settings: Check your Player Settings under the Resolution and Presentation tab. Sometimes toggling options like Full Screen Mode can make a difference.
      • Script it Out: You can try adding this small script to your project to enforce a window size:
              
            using UnityEngine;

            public class WindowManager : MonoBehaviour {
                void Start() {
                    Screen.SetResolution(1280, 720, false); // Set your desired width and height
                }
            }
      • Test Different Resolutions: Sometimes simply changing the resolution settings in the game view can help. Experiment with window sizes that might work for your workflow.
      • Look into Config Files: You can check the ProjectSettings folder, specifically the EditorBuildSettings.asset. There might be settings there that affect window modes.

      Also, keep an eye on Unity forums and communities; someone might have stumbled across the same issue and could have a fix that’s not widely known yet.

      Hope some of these ideas help you out without forcing you to upgrade! Good luck getting your project back on track!

    2. This is a common issue with Unity versions earlier than 2023, where setting the project to “Maximized Window” mistakenly forces a fullscreen state. A simple workaround involves manually adjusting the window via scripting at runtime using Screen.SetResolution(). For example, you can insert this line in a script that’s loaded at startup: Screen.SetResolution(1280, 720, false);, specifying your desired screen width and height, with false ensuring windowed mode instead of fullscreen. This small line of code enforces your desired windowed dimensions and can often bypass Unity’s built-in bug.

      Another method worth trying is directly modifying your project’s configuration file: open the file ProjectSettings/ProjectSettings.asset in a text editor, locate the fields relating to resolution and fullscreen settings, and manually verify or adjust them. Be sure to back up your files before changing settings manually. Combining the above code adjustment approach with manual intervention in your settings file typically provides a robust solution without requiring extensive reworks or Unity upgrades.
