Seeing a single black frame before my game actually starts

So, I've come across a single black frame after the "card/card-pressed" & "launchImages". It's right before the game actually starts:
playdate-20251006-120625

My "card", "card-pressed" & "card-highlighted" images are all 350x155.

My "launchImages" are all 400x240 with a shrinking transparency, like the Sample "Level 1-1" game has it.

This is my folder set up:

The same thing happens if I run the version that's exported directly from Pulp, without any modifications:
playdate-20251006-204500

I've made sure all of the card/launch images match up perfectly to the game's actual title screen in terms of positioning of various parts of the card/launcher images. Am I missing something/incorrectly named a file? I don't have any other image files in the pdx file except those within the "SystemAssets" folder.

This is the imagePath in my pdxinfo file: imagePath=SystemAssets/

I've attached a zip of that folder too: SystemAssets.zip (90.8 KB)

Any assistance would be amazing :playdate_happy:

So, to rule some things out. I've tried the following:

  • Using just a static launchImage instead of launchImages​:
    playdate-20251006-203753

  • Using no launch images whatsoever & then running a version of the game directly exported from Pulp, without any modifications
    playdate-20251006-204500

  • Changing the start room to something else:​
    playdate-20251007-000843 copy

  • These all do happen when running the game on my Playdate (converted a Mirror clip to gif via ffmpeg):
    Playdate 2025-10-07_00:05:25

Not sure what else could be causing this issue :thinking:

What's weird is that I can run the "Level 1-1" sample and there's no single black frame present:
playdate-20251007-124226_2x

This sample is made in Lua so, maybe my issue is with Pulp itself?

Worked with Panic/Playdate support and found a possible solution to the bug :playdate_happy: :
