I am trying to run Pixel Composer 1.21 (latest stable) on Ubuntu 24.04 Linux.
I have tried running it via Steam and the itch.io executable, but neither works.
The issue is that when I launch the program, a window appears, but its content is whatever was behind the window where it opened (for example, if it opened behind a game, that game appears inside the window). It also always opens at a size of 1600x800; this happens with both the Steam version and the itch.io executable.
Here is a photo of the issue:

Update: Now, for some reason, the application reopened after I took the screenshot (note that I had restarted the PC before taking the shot and disabled Steam’s forced compatibility mode).
This might have been a glitch caused by some random issue, but I’m mentioning it just in case.
Another update: After running the program, anything that uses the file browser (such as importing an image) no longer works; the file browser simply doesn’t open.
For example:
- It won’t let me add an image node.
- I can add an export node, but if I try to select a directory using the file manager, nothing opens.
