TWINE: Glitched background during main menu idle credits (Regression, Sort of)

Reported by: antoniou79 Owned by: mgerhardy
Priority: normal Component: Engine: TwinE
Version: Keywords:
Cc: Game: Little Big Adventure

Description (last modified by antoniou79)

This was tested on Windows 10 with a recent build of ScummVM 2.9.0git from master HEAD and the GOG version of Little Big Adventure.

The issue is that, during the credits that play after the main menu has been idle, half of the background is black and the other half is the bottom half of the main menu.

How to reproduce: Launch the game, wait till it gets to the main menu, then leave it on idle for about a minute. The game's credits will start rolling automatically, and the end credits music is playing.

I am attaching screenshots of the low res and high res credits. (The high res credits are "expected" to be more glitchy since due to another issue (https://bugs.scummvm.org/ticket/13134), the yet unused NPCs are seen all grouped to the left -- this ticket is not about that issue).

This looks like sort of a regression from what happens in 2.8.1, albeit the daily build has some improvements.

In comparison the 2.8.1 ScummVM rolls the credits after the main menu has been idle for only 15 seconds (too fast), and also no music is playing during the credits. But it has a full black background.

85d3666364bc75966e992cc5ebd07b6a585eed6c (commit is unrelated to twine) during bisecting I found this commit that is somehow related - leaving the credits scene with esc will enter the menu with the wrong palette.

The removal of the _engine->_screens->clearScreen(); call most likely - but I can't find this in the original sources - need to investigate
