#11160 new defect

WME: Engine doesn't use correct screenmode

Reported by: raziel- Owned by:
Priority: normal Component: Engine: Wintermute
Version: Keywords:
Cc: Game: Wintermute


ScummVM 2.1.0git (Sep 21 2019 15:43:15)
Features compiled in: Vorbis FLAC MP3 RGB zLib MPEG2 Theora AAC A/52 FreeType2 JPEG PNG cloud (servers, local)

When switching to the game screen the correct resolution is not picked up correctly, rather the game screen is squeezed inside (or enhanced to) the resolution the user used in ScummVM's launcher when starting the game.

This is with SDL(1/2) and tested with AmigaOS4 and Linux and a launcher resolution of 640x480 while starting a WME game that uses a screen resolution of 800x600.

Every Wintermute game is affected (some more, some less), but one game is particularly easy to check against, since it starts with a (in-game) window filled with text and a resolution of 800x600:

Chivalry is Not Dead (Windows/English)

Needless to say that if i use the game's correct resolution in the launcher BEFORE starting the game, the game will be rendered perfectly. (But i don't know every resolution of every WME game and i also think this should be handled by ScummVM on-the-fly.)

The behaviour changed a little since opening this item.
With 2.3.0git I know get a perfect game screen, but cramped to the left bottom of the whole screen instead of fullscreen.
That is with every wme game I tried.

It seems as if my systems resolution 2560x1440 is always used as base, instead of switching to resolution that is near the games resolution.
Window is fine btw

Adding to this a "workaround"
If i switch to window (after the broken game screen shows up) and back the screenmode/game screen gets fixed.

Hi raziel-!

Sorry for being missing for a long time, now I'm back to fixing WME bugs.

There are 2 things i'd like to mention about the current issue:

  1. WME has 3 different renders - Software / OpenGL / OpenGL with shaders.

I can reproduce behaviour similar to no_title_008.png with non-Software renders on Windows.
I'll post a separate bug on this, tagged with "WME3D:" prefix, since 2D games are using Software rendering by default, if not explicitly changed in global or per-game options.

  1. I think I have noticed a reason why screen was stuck at launcher size - there was an unnecessary call to initGraphics(800, 600, &format) before initializing game graphics. Can you please check if anything gets better with Software render after applying this fix: ?

Heh, no problem.
There are far more important things out there :-)

Thank you for the link.
I'll try that as soon as I'm back home (following weekend) and give feedback.
