Constant input towards left direction after using the in-game song editor

[nosebeggar]

Issue type: Bug report

Actual behaviour

After editing a song in-game to adjust the timings and leaving the editor with escape the game constantly presses towards the left (I think), which means the menu goes absolutely crazy, this can be temporarily stopped by clicking one of the top-right buttons in the song selection menu (modifiers for example) and then not using the mouse to navigate anymore. As soon as you click, which I assume gives focus to a certain element, the menu goes wild like a merry-go-round again.

Expected behaviour

I think that is self-explanatory. If the dev finds out and knows a workaround I can use until the bug is fixed, please name it, I need to fix dozens of songs and i am going crazy.

Hi, thanks for the report.
Will try to reproduce this.

In the meantime, please make sure that your hardware is not the root cause.

• If you switch to a separate text editor app (e.g. Notepad) does the cursor move to the left as well?
  • If yes, the input is wrong on OS level
• Is there any controller connected with fishy inputs?

[nosebeggar]

Hi, nope this is only in-game, not OS-level.
No controllers connected whatsoever

Thanks for the detailed bug report and the video.
Unfortunately, I am unable to reproduce this issue.

Did you use the arrow keys or other navigation inputs in the song editor? Does not look like it.

In the log, the only suspicious entry is when leaving the song editor.

SongEditorAlternativeAudioPlayer is to play vocals/instrumental audio, which seems to be missing.
Is there any difference when you split the audio such that vocals/instrumental audio exist?

Weird bug indeed.

[nosebeggar]

No I didn't use the arrow keys in the editor. I can no longer help with troubleshooting because I refunded it as long as I could. It was unplayable like this and had quite a few other bugs I didn't bother to report. I now use USD.
