Road Rash: very minor HUD related (?) issue

[AvinashReddy3108]

Issue Details

OS: Arch Linux (game is run via WINE version wine-7.22 (Staging)) Game: Road Rash (ROADRASH.EXE) cnc-ddraw version: v4.9.0.0 (Used WINEDLLOVERRIDES='ddraw=n,b' ["native, builtin" override])

Configuration (ddraw.ini)

```ini ; cnc-ddraw - https://github.com/FunkyFr3sh/cnc-ddraw [ddraw] ; ### Optional settings ### ; Use the following settings to adjust the look and feel to your liking ; Stretch to custom resolution, 0 = defaults to the size game requests width=0 height=0 ; Override the width/height settings shown above and always stretch to fullscreen ; Note: Can be combined with 'windowed=true' to get windowed-fullscreen aka borderless mode fullscreen=false ; Run in windowed mode rather than going fullscreen windowed=false ; Maintain aspect ratio maintas=false ; Windowboxing / Integer Scaling boxing=false ; Real rendering rate, -1 = screen rate, 0 = unlimited, n = cap ; Note: Does not have an impact on the game speed, to limit your game speed use 'maxgameticks=' maxfps=-1 ; Vertical synchronization, enable if you get tearing - (Requires 'renderer=auto/opengl/direct3d9') ; Note: vsync=true can fix tearing but it will cause input lag vsync=false ; Automatic mouse sensitivity scaling ; Note: Only works if stretching is enabled. Sensitivity will be adjusted according to the size of the window adjmouse=true ; Preliminary libretro shader support - (Requires 'renderer=opengl') https://github.com/libretro/glsl-shaders ; 2x scaling example: https://imgur.com/a/kxsM1oY - 4x scaling example: https://imgur.com/a/wjrhpFV ; shader=Shaders\cubic\catmull-rom-bilinear.glsl ; Window position, -32000 = center to screen posX=-32000 posY=-32000 ; Renderer, possible values: auto, opengl, gdi, direct3d9 (auto = try direct3d9/opengl, fallback = gdi) renderer=auto ; Developer mode (don't lock the cursor) devmode=false ; Show window borders in windowed mode border=true ; Save window position/size/state on game exit and restore it automatically on next game start ; Possible values: 0 = disabled, 1 = save to global 'ddraw' section, 2 = save to game specific section savesettings=0 ; Should the window be resizable by the user in windowed mode? resizable=true ; Enable linear (D3DTEXF_LINEAR) upscaling filter for the direct3d9 renderer d3d9linear=true ; Enable upscale hack for high resolution patches (Supports C&C1, Red Alert 1 and KKND Xtreme) vhack=false ; cnc-ddraw config program language, possible values: auto, english, chinese, german, spanish, russian, hungarian, french configlang=auto ; Where should screenshots be saved screenshotdir=.\Screenshots\ ; ### Compatibility settings ### ; Use the following settings in case there are any issues with the game ; Hide WM_ACTIVATEAPP and WM_NCACTIVATE messages to prevent problems on alt+tab noactivateapp=true ; Max game ticks per second, possible values: -1 = disabled, -2 = refresh rate, 0 = emulate 60hz vblank, 1-1000 = custom game speed ; Note: Can be used to slow down a too fast running game, fix flickering or too fast animations ; Note: Usually one of the following values will work: 60 / 30 / 25 / 20 / 15 (lower value = slower game speed) maxgameticks=0 ; Windows API Hooking, Possible values: 0 = disabled, 1 = IAT Hooking, 2 = Microsoft Detours, 3 = IAT+Detours Hooking (All Modules), 4 = IAT Hooking (All Modules) ; Note: Change this value if windowed mode or upscaling isn't working properly ; Note: 'hook=2' will usually work for problematic games, but 'hook=2' should be combined with renderer=gdi hook=4 ; Force minimum FPS, possible values: 0 = disabled, -1 = use 'maxfps=' value, -2 = same as -1 but force full redraw, 1-1000 = custom FPS ; Note: Set this to a low value such as 5 or 10 if some parts of the game are not being displayed (e.g. menus or loading screens) minfps=0 ; Disable fullscreen-exclusive mode for the direct3d9/opengl renderers ; Note: Can be used in case some GUI elements like buttons/textboxes/videos/etc.. are invisible nonexclusive=false ; Force CPU0 affinity, avoids crashes/freezing, *might* have a performance impact singlecpu=true ; Available resolutions, possible values: 0 = Small list, 1 = Very small list, 2 = Full list ; Note: Set this to 2 if your chosen resolution is not working, set to 1 if the game is crashing resolutions=0 ; Child window handling, possible values: 0 = Disabled, 1 = Display top left, 2 = Display top left + repaint, 3 = Hide ; Note: Disables upscaling if a child window was detected fixchilds=2 ; Set the precision for Direct3D9 floating-point calculations to the precision used by the calling thread ; Note: Enable this if there are desyncs in online games fpupreserve=false ; Undocumented settings d3d9_adapter=0 opengl_core=false d3d9on12=false guard_lines=200 max_resolutions=0 limit_bltfast=false game_handles_close=false accuratetimers=false fixpitch=true fixwndprochook=false novidmem=false locktopleft=false lock_surfaces=false releasealt=true gdilinear=false allow_wmactivate=false dinputhook=false flipclear=false fixmousehook=false bpp=0 ; ### Hotkeys ### ; Use the following settings to configure your hotkeys, 0x00 = disabled ; Virtual-Key Codes: https://docs.microsoft.com/en-us/windows/win32/inputdev/virtual-key-codes ; Switch between windowed and fullscreen mode = [Alt] + ??? keytogglefullscreen=0x0D ; Maximize window without frame = [Alt] + ??? keytogglemaximize=0x22 ; Unlock cursor 1 = [Ctrl] + ??? keyunlockcursor1=0x09 ; Unlock cursor 2 = [Right Alt] + ??? keyunlockcursor2=0xA3 ; Screenshot keyscreenshot=0x2C ```

First things first, this is the ONLY wrapper that works perfectly for this game on my Linux system (huge kudos for that) [even the shaders work perfectly, except for this HUD issue given below].

Now onto the one minor issue:

When using cnc-ddraw, there's this box area that's appreoximately the same as the HUD area in race that's unaffected by the shaders (I know shader support is not stable yet) and produces a screen tearing like effect (this effect even exists when I don't use any shaders)

Screenshot (without cnc-ddraw):

Screenshot (with cnc-ddraw):

Edited screenshot

I marked the screenshot to show the affected region (region below the blue line)

Notice how the white line of the road [near the blue line I marked] is sliced more than it should be (compared to the screenshot without cnc-ddraw). I have marked that with a red circle..

I'll appreciate any help I can get to try to fix this, and am ready to provide any logs required.

Here's another screenshot (I used the handheld/gbc-gambatte-color.glsl shader) Also changed the HUD (can be done by F10 key in race)

Notice how the HUD area is unaffected by the shader, can be seen from the fire hydrant in the lower left of the screen

Used the ddraw.dll from #44, here's the debug logs it generated.

With some tinkering of the config file, I have figured out the fix.. Simply use fixchilds=1, and the problem is solved..

Even custom shaders work perfectly now.
