Does opengl (no iltering) work?

I can also confirm that the Kirben build fixes the mouse cursor issue.

Hello, nice people of this forum. This is my first post and of course it has to be a problem even if I have happily used ScummVM for many years. Thank you to everyone who has contributed.

Now the rant.

Using Kirben builds doesn't work for me. The behaviour is exactly the same whether I use ScummVM 1.8 (the build that comes with Kyrandia 3 from GOG) or any of the latest builds (Kirben or dailybot).

This is the INI file for the latest game, Kyrandia 3 - Malcolm's Revenge, displaying the issue (only custom option is the gfx_mode set to opengl_linear, no filtering):

Code: Select all

&#91;scummvm&#93;
last_fullscreen_mode_height=2880
speech_volume=192
native_mt32=false
midi_gain=100
last_fullscreen_mode_width=5120
talkspeed=60
gfx_mode=opengl_nearest
subtitles=false
multi_midi=false
fullscreen=true
themepath=E&#58;\GOG Games\Legend of Kyrandia - Malcolms Revenge\ScummVM\

music_driver=auto

savepath=E&#58;\GOG Games\Legend of Kyrandia - Malcolms Revenge

helium_mode=false
gameid=kyra3
language=en
platform=pc
studio_audience=true
guioptions=sndNoMIDI vga gameOption1 gameOption2 gameOption3 lang_English

In windowed mode it works fine.
Additional info: it happens in computers with and without touchscreen or touchpad. It happens switching among several mice. I also place the start of the problem around the time when Windows 10 FCU was installed.

I will try to debug the problem if I manage to set up a ScummVM development environment.

EDIT: Launching the game from the ScummVM GUI makes the problem go away with any configuration that I have tested. It seems it is the GOG shortcut (scummvm -c path/to/ini.file game_name) which causes the issue for some reason. I have also realised that OpenGL nearest is no longer required for a non-filtered experience. Great!

I can also confirm the Kirden build fixed the mouse jumping issue, thanks for all the responses!

try this Kirben build, not the buildbot ones it worked for me

You can find them at http://scummvm.org/downloads/scummvm-win32.exe

I could reproduce the issues with the buildbot dailys, but not with the Kirben builds. The thing is that the buildbot still uses SDL 1.2.15 which has a lot of issues with the current Windows version while the builds made by Kirben have SDL2. SDL1 is not maintained anymore and severly outdated, while SDL2 is the current version. (SDL is the library we use for video, sound and input handling on most of our supported platforms).

mmmmmmmmmmm... i have download this:

But it's at win32......... i prefer to use the w64 but there's no Kirben build.......

Hmm, I have been looking for weeks now for a scummvm version that includes all the 2.0 game compatibilities, but doesn't have these two problems:

Mouse Jumping (as described in this thread) & graphical artefacts with bilinear filtering turned on.

The second problem I encountered on two different freshly updated Win 10 systems by now. The last line of the picture gets depicted on the opposite side of the screen, leading to quite annoying artefacts/glitches.

I noticed the other daily builds seem to have gotten rid of that problem by now, but they all let the mouse jump around to almost unplayability of many games at my systems. Now the Kirben build has proper mouse, but the bilinear artefacts are there again.

I know I could just turn off bilinear filtering or choose OpenGL to avoid artefacts, but all other picture modes seem to be either too sharp/edgy or too blurry to be enjoyable.

Have I missed some proper ScummVM version that's already around? Or shall I have to wait for further updates. Right now, unfortunately both problems are simply too severe to really enjoy the otherwise great and holy ScummVM platform at the moment...

That sounds like https://bugs.scummvm.org/ticket/9643, which was a bug in SDL, and has been fixed, but too late for the ScummVM 2.0.0 release. There is no SDL release with this fix yet (I guess this will be available in SDL 2.0.8, whenever it is released).

Builds that use the older SDL 1.2 do not have this issue because they do not let SDL do the scaling. But they will indeed have the mouse issue described here.

Something that might work (according to the SDL documentation) is to use the Kirben build and set the SDL_RENDER_DRIVER windows environment variable to direct3d11 or opengl. Otherwise, until SDL 2.0.8 is available, you might need to compile ScummVM (or find somebody who can do it) after modifying the ScummVM source code as described in the link I gave above to work around the bug in SDL.

Thanks a lot for the reply.

Modding the SDL environment to DX3d11 sounds good. I would like to give that a try.

Is there a link to a short tutorial how to do this?

(I actually don't even know what SDL really is, I just read about the term here in the forum. So compiling anything by myself actually scares the non-technical noob in me right now...)

SDL is a third party software library we use to create and manage the scummvm window, including the rendering of the window content to the screen.

Setting an environment variable is actually not specific to SDL. On Windows you would do it by going to the System control panel, then go to the Advanced system settings, and in the Advanced tab click on the Environment Variables... button. You can then edit, or add if it does not yet exist, the SDL_RENDER_DRIVER variable. Those instructions are based on Windows 7, they may differ for other versions of Windows.

Ok, I found the windows panel and created SDL_RENDER_DRIVER entry.

But I'm not so sure which value to insert there. I just tried typing in "direct3d11", but nothing changes, I still get the artefacts when bilinear f. is selected.

What is the value to type in for setting the SDL driver to driect3d11?

Mouse cursor jumps randomly to corners of the screen, win10

Solved with Kirden build

Any new vs. that fixes mouse problems AND bilinear f.?
