DOUBLE Mouse Pointer on sdl screen

Guys is this only with me but im geting Double mouse pointers on any SDL screen (like scummvm ,JA2)

i get the amigaos poiner and the game pointer floating around whats very anoying with playing games .


How can i solve this?

No immediate idea, but what graphics adapter do you use? Also ScummVM and JA2 are both dynamically linked, at least what I have installed, so it occurred to me the SDL comes from wherever - which SDL build (libSDL-1.2.so) do you use? (Example of SDL program from OS4Depot statically linked, which uses mouse: lincity-ng)

im using a radeon hd card

and and the sdl .so thingie i use is the latetst build. 2.13.1.3

with lincity i didnt get it as far i can remember.

but with ufoAI scummvm latetst and JA2 are the ones that i can name quickly.

nomatter what screen mode i choose from 640 , 800 , 1024 and so on.

Incidentally, UFOAI is also dynamically linked. I'd start by trying some other SDL.

like wich one???

i only have my amiga one x500 for 1 week so im new with this kind sdl work and sources


i played with some sdl.so version but all do the same.

linecityng doesntt have double mouse pointers i checked it just now.


ja2 still have and and also scummvm

that's strange. also with the latest version (and with the previous) i never see this problem.
BTW you can find the latest versione here:

http://code.google.com/p/os4sdl/

i tried that one also.


i also had that same tthing as i remeber good on my os4 classic.

but ppc cpu broke down so i cant check it

dont you guys have a screen made for sdl extra to workbench by prefs screens or something?

no. i've only used Workbench screen for all SDL apps

I found out the double mouse pointer is only present with the RadeonHD driver at home, not on others systems.

Same problem here with my RadeonHD 4800 and Discworld.

A quick fix would be to do a script to backup and restore the mouse pointer (if you use 32bit) when you run scummvm. eg. create a single black pixel icon and copy it to env/sys/def_pointer.info, run scummvm then copy envarc:sys:def_pointer.info back to env:sys/ when scummvm quits.

Just tried it, works fine. the script I used was:


copy def_pointer.info env:sys force
Stack 600000
ScummVM
copy envarc:sys/def_pointer.info env:sys force


Def_pointer.info is 1 black pixel and stored in the scummvm drawer.

Add an tool icon, make sure script is ticked and run from shell.

Could that mean that blanking (hiding) of the mouse pointer is not supported?

@ChrisH

Looks like it, mouseblanker doesn't work either, I'll BZ it.

well i tried it and it works but im getting a workbench requester of close all screens so when i stop ea scummvm my mouse pointer is still 1 dot until ill find the cancel button.

how can i fix this?

hmmm... not had that problem, I suppose you could try something like http://aminet.net/util/cdity/MarkMouse.lha until you find out what causes the problem or if you have the right hardware install the updated RadeonHD driver which cures the problem here.

According to the release notes of the latest RadeonHD driver from ACubes website, this problem is fixed.
