ebiten: Bug: text flickering when resizing screen.

Problem

Strange text flickering with minimal settings.

Happens with this:

text.Draw()
ebitenutil.DebugPrintAt()
text.DrawWithOptions()

And this:

ebiten.SetWindowResizingMode(ebiten.WindowResizingModeEnabled)
ebiten.SetFPSMode(/* any value, can be ignored */)
if err := ebiten.RunGame(/* your text rendering functions */); err != nil {
	log.Fatal(err)
}
