AnimatedImageStrips on the HUD sometimes stop animating after clicking on the pause menu

[vrad-exe]

If an AnimatedImageStrip is used on the HUD, it will work correctly until the pause menu is opened and closed, at which point it may become permanently frozen. This is inconsistent but seems to be more likely to happen if things in the pause menu are clicked before unpausing.

Here it is with my WIP panorama save indicator as an example:

p2ce_NixvonhKHj.mp4

Manually setting the image's animating boolean back to true through scripting doesn't work, the only way to restart the animation seems to be reloading the entire HUD using the dev keybinds.

This probably stems from Panorama doing some perf stuff and stopping painting which breaks the frame animation loop. Not sure why it's so inconsistent, but that much is true. Manually firing the event to move it to the next frame will desync the animation time (if the paint loop didn't break. If it did break, this works normally) because the way it works is that for every time it paints, it sets up a timer (similar to $.Schedule) to advance the frame. Forcing the frame to advance would force a repaint (good), but also start another timer (not so good).

So I was curious how to get it to behave and I can't seem to get it stuck again:

$.RegisterForUnhandledEvent('GameUIStateChanged', (old: GameUIState, now: GameUIState) => {
	if (now === GameUIState.INGAME) {
		$<AnimatedImageStrip>('#Spinner')!.SetReadyForDisplay(false);
	}
});

Usually I could get it to stick after a few tries but this seemed to remedy it. You could try on your side to see if it also does this for you (though I wouldn't be surprised if it didn't).

Alternatively this can also force a repaint. Need to make sure it goes invisible and stays that way for a frame.

$.RegisterForUnhandledEvent('GameUIStateChanged', (old: GameUIState, now: GameUIState) => {
	if (this.fadeTimer && now === GameUIState.INGAME) {
		$<AnimatedImageStrip>('#Spinner')!.visible = false;
		$.Schedule(0.01, () => {
			$<AnimatedImageStrip>('#Spinner')!.visible = true;
		});
	}
});

The first option you listed seemed to work for me, though it would still be nice to have a proper code fix for this so that the workaround doesn't have to be added to every HUD panel that uses animated images
