Upgraded sdl package breaks mouse in OpenTTD


From Slackware64 14.0 Changelog.txt

Code:
Fri Feb  8 03:57:05 UTC 2013
(...)
patches/packages/sdl-1.2.14-x86_64-6_slack14.0.txz:  Rebuilt.
  Patched mouse clicking bug.
This version of sdl makes the mouse cursor disappear whenever I click somewhere inside OpenTTD's (it's a game) window.

When I reverted the package back to the one originally shipped with Slackware, the bug disappeared.

So I guess the new sdl fixed some clicking bug, but introduced another one.

Which openttd?

I have here 1.3.1 on current which has SDL 1.2.15 with the same patch applied and I don't see the bug you describe.

Some possibilities

1. Recompile of openttd required
2. Newer openttd required
3. Newer SDL required (any compatibility issues? only a minor version jump)
4. Some other library or even X at play

Maybe there were some other changes in 1.2.15 that fixed the issue I'm having with 1.2.14-6.

I'll just stay with SDL 1.2.14-5. It's not a big deal.

For clarity's sake: Are you folks testing with the game windowed or maximized?

I know that certain SDL games were handling the mouse a bit weird in window mode but totally fine maximized (remembering OpenTTD and Battle for Wesnoth). Checking real quick, BFW seems fixed, but not OpenTTD.

Edit: Ack. I've got an old OpenTTD. I'll test the new one when I get back home...

I don't see this issue on Slackware64-14.0 (with latest patches) and OpenTTD 1.3.1. The mouse works fine in windowed mode.

Code:
chess@slack 11:48 PM ~ $ ls /var/log/packages | grep sdl
sdl-1.2.14-x86_64-6_slack14.0
sdl-compat32-1.2.14-x86_64-5compat32
chess@slack 11:49 PM ~ $ ls /var/log/packages | grep openttd
openttd-1.3.1-x86_64-1_SBo

There's no difference when running the game in windowed or fullscreen mode. The cursor disappears in both cases.

Code:
bash-4.2$ chpa sdl
sdl-1.2.14-x86_64-6_slack14.0
sdl-compat32-1.2.14-x86_64-5compat32
bash-4.2$ chpa openttd
openttd-1.3.1-x86_64-1_SBo
chpa (check package) is just my alias for ls /var/log/packages/ | grep -iE

Thanks for your reply Chess (I'm listening to Linux Reality each night, great show
At least we know it's something with my system and not a general issue.

I don't have the energy to look for the source of the problem, especially if I can easily bypass it by sticking with the previous build of SDL.

Thanks guys.

Have you tried rebuilding OpenTTD against the updated SDL packages?

Yes, ReaperX7.

I've had SDL updated since it was released in February and I've built OpenTTD with sbopkg only a few days ago.

However, since both you and earlier wildwizard suggested to rebuild the game, I just did the following steps:

1. slackpkg upgrade-all (which updated SDL from -5 to -6)
2. removepkg openttd
3. sbopkg -> build and install openttd

And the same thing happens.

Next I downgraded to sdl-1.2.14-x86_64-5.txz: mouse works fine.

I've even tried downloading sdl-1.2.14-x86_64-6_slack14.0.txz from another mirror, just in case the file was corrupted.

Thanks! Glad to hear it is still (somewhat) standing the test of time, although I am sure a lot of it is pretty outdated by now. :-)

This is a strange bug you are encountering and maybe it's more of a graphics driver or something. I really don't know. I'm on a stock Slackware64-14.0 on my Lenovo laptop with Intel 4000 Ivy Bridge graphics on the 3.8.4 kernel FWIW.

At least you're able to find a workaround by downgrading sdl. Post back if you ever find the answer.
