Summary0000124: void-like garbage flashed on-screen when exiting maps in KDIZD online
DescriptionEvery time I exit a map in KDIZD when there's a map list without the custom intermission map in it, the screen is flashed with void-like garbage before entering the next map. It also happens without a custom map list, but it's most noticeable when there is one.

I don't know how to reproduce it, but I think that it has something to do with the huge maps in general and their loading times.

The maps have 'nointermission' defined in them inside the MAPINFO lump.
Steps To ReproduceStart a local KDIZD with z1m1 and z1m2 in the map list. Connect a client to the server. Once in-game (not spectator), use 'nextmap' in the server console to alternate between the maps.
Additional InformationI managed to snap a screenshot of the effect.

 It also happens in "Zombie HORDE". With the 'idmypos' cheat enabled, I can see that the player spawns much higher above the floor height.

EDIT:

FYI, this effect doesn't occur online in GZDoom 323 when using the 'changemap' command. And with the 'idmypos' cheat enabled, I can see that the player doesn't spawn above the floor height either.

 I think it might also have to do with the map being a bit large and taking a time to load but I'm not sure. I remember observing this with big maps back in the day.

 If in debug mode I enable cl_showonetickpredictionerrors, I get this console when the void garbage happens:


(22322) WARNING! ServerXYZ does not match local origin after 1 tick!
     X: 29097984, 1048576
     Y: -361234432, -16252928
     Z: -2621437, 1572864


I hope this helps..

 I get the feeling that this is caused by the server being ahead of the player during map changes and making the player use the new map start x/y/z coordinates while the player is still in the former map locally, since you consistently appear at the same position in the void before the map change.

And yes, I can confirm that this is the case. See attached screenshot.
