Solved Mouse glitching around when using ddraw/glide

I can't seem to be able to start fullscreen by using Game.exe in the game folder nor by fullscreen setting in ddraw.
It works however with 3dfx -windowed unchecked. Then all of the options - Game.exe, ddraw, d2Vidtst - run fullscreen. In case of ddraw it doesnt matter if I set windowed while 3dfx has windowed unchecked. Anyways, in fullscreen the mouse is working fine.
I have the autodownloaded ddraw.ini (deleted the one I changed just to be sure)

; ### NOTE TO DIABLO 2 LEGACY PLAYERS ###

; To enable upscaling via shaders in -fullscreen mode- just set 'fullscreen=true' and 'windowed=false'
; To enable upscaling via shaders in -windowed mode- just set 'fullscreen=false' and 'windowed=true' then start the game and resize your window or set 'width=' and 'height=' to the desired window size

; ### 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=true

; Maintain aspect ratio - (Requires 'handlemouse=true')
maintas=false

; Windowboxing / Integer Scaling - (Requires 'handlemouse=true')
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=125

; 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 - (Requires 'handlemouse=true')
; Note: Only works if stretching is enabled. Sensitivity will be adjusted according to the size of the window
adjmouse=false

; 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\xbr\xbr-lv2-noblend.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=opengl

; Developer mode (don't lock the cursor)
devmode=true

; 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=1

; Should the window be resizeable by the user in windowed mode?
resizeable=true

; Enable C&C video resize hack - Stretches C&C cutscenes to fullscreen
vhack=false

; Enable linear (D3DTEXF_LINEAR) upscaling filter for the direct3d9 renderer (16 bit color depth games only)
d3d9linear=true



; ### 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=false

; 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

; Gives cnc-ddraw full control over the mouse cursor (required for adjmouse/boxing/maintas)
; Note: Set this to 'false' if your cursor becomes invisible at some places in the game
handlemouse=true

; 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' must be combined with renderer=gdi
hook=4

; Force minimum FPS, possible values: 0 = disabled, -1 = use 'maxfps=' value, 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

3dfx I havent touched, except for the windowed option, I can send screens or settings file (I couldn't find one) if necessary.
Edit 2: It seems to me that glide is always running, no matter which option I chose (except for -w)

Ok, so the solution seems to be... to actually run D2VidTst.exe in the game folder and select ddraw. Now I can actually see the difference between glide and ddraw. When using ddraw the mouse is not glitching, though the problem persist with glide. Funnily enough I also tried using the -w -3dfx tags on Game.exe shorcut and mouse is not glitching in that scenario. Anyways problem solved, thanks for the help
