Width and height are checked for zero or less on initialisation: https://github.com/eclipse-platform/eclipse.platform.swt/blob/7c818d6b4727f754a0c64e99b15e74ea97c52031/bundles/org.eclipse.swt/Eclipse%20SWT/cocoa/org/eclipse/swt/graphics/Image.java#L1446-L1449 https://github.com/eclipse-platform/eclipse.platform.swt/blob/7c818d6b4727f754a0c64e99b15e74ea97c52031/bundles/org.eclipse.swt/Eclipse%20SWT/win32/org/eclipse/swt/graphics/Image.java#L2078-L2082 https://github.com/eclipse-platform/eclipse.platform.swt/blob/7c818d6b4727f754a0c64e99b15e74ea97c52031/bundles/org.eclipse.swt/Eclipse%20SWT/gtk/org/eclipse/swt/graphics/Image.java#L1245-L1248 Is the size of 0,0 set in some other place in `Image`?

Try using a paint listener. Otherwise the image will be tiled (this is how images in Composites are rendered): ``` import org.eclipse.swt.SWT; import org.eclipse.swt.graphics.Image; import org.eclipse.swt.widgets.Composite; import org.eclipse.swt.widgets.Display; import org.eclipse.swt.widgets.ScrollBar;...

@tmssngr As a matter of interest this is also causing erratic behaviour in SmartGit. I don't know if you want to take a look at this as well?

@jukzi Wrong label. Should be macOS.

Actually, it's the same for the latest 4.33 I-builds. Seems to be the case since 4.31. Verifying the jars from 4.30 gives `jar is unsigned`.

Strange. The jars from `I20240713-0130` are unsigned and the ones from `I20240713-1800` are signed (although incorrectly).

Is the bug in the SWT Control Example code or in SWT itself?
