[TF2] Custom Menu hud flash original background before custom background

[xacatis]

Giving in custom MainMenuOverride.res, all images to same one and have custom title_invasion.vtf "image" "../console/title_invasion" One time it flah to real background image invasion and then back to custom on server disconnected by user

This sounds like the expected behavior if an asset is slow to load.

For custom HUDs what you should do it edit scripts/chapterbackgrounds.txt to only use the background you're overwriting with your custom one. So if your custom background is replacing background_upward then your chapterbackgrounds file would look like this.

"chapters"
{
	1	"background_upward"
	2	"background_upward"
	3	"background_upward"
	4	"background_upward"
}

"BackgroundMaps"
{
	1	"background_upward"
	2	"background_upward"
	3	"background_upward"
	4	"background_upward"
}

Then in resource/ui/statsummary.res set background_upward as the main background for the loading screens.

"MainBackground"
{
	"ControlName"	"ImagePanel"
	"fieldName"		"MainBackground"
	"xpos"			"0"
	"ypos"			"0"
	"wide"			"0"
	"tall"			"0"
	"visible"		"0"
	"enabled"		"0"
	"image"			"../console/background_upward"
	"scaleImage"	"1"
}

In short, I don't think this is something that needs looking into by the developers.
