Go Version (go version)

go version go1.21.1 darwin/arm64

What steps will reproduce the problem?

A call to ebiten.SetFullscreen() passing either true or false.

The output will also repeat if I Alt-Tab from the fullscreen game to or from another application on the same monitor, but not a different monitor. Switching workspaces on that monitor does the same.

Test case code (Press F to toggle fullscreen in-game)

go package main import ( "github.com/hajimehoshi/ebiten/v2" "github.com/hajimehoshi/ebiten/v2/inpututil" ) type Game struct { } var fullscreen = false func (g *Game) Update() error { if inpututil.IsKeyJustPressed(ebiten.KeyF) { fullscreen = !fullscreen ebiten.SetFullscreen(fullscreen) } return nil } func (g *Game) Draw(screen *ebiten.Image) { } func (g *Game) Layout(outsideWidth, outsideHeight int) (int, int) { return 960, 540 } func main() { ebiten.SetWindowSize(960, 540) ebiten.SetWindowTitle("Fullscreen Test") ebiten.RunGame(&Game{}) }

What is the expected result?

No output to console.

What happens instead?

Something like the following message is output to console when I enter fullscreen:

Does this cause crashes?

[venning]

No crashes. I notice no unusual behavior except for the console logs.

Edit: If I wasn't clear in my original post, multiple actions like entering/exiting fullscreen or switching workspaces will result in additional outputs to the console.

A new addition to the logs:
