Bug Description

Hi!

I am working on project mono.xna, which ports microsoft .NET game framework to Mono.
We are using Tao framework for C# bindings of OpenGL, SDL and others.

Mono.Xna games are working PROPERLY on Ubuntu 9.04 AND Nvidia graphics cards. But problems are ATI Radeon cards.

I have Radeon 9600m (RV350) on my laptop.

I still don't know where is the bug. It has to do something with:
- Ubuntu 9.10
- ATI Radeon driver (opensource)
- SDL (tao framework)
- DevIl library (tao framework)

This is log what I get if have "libtaoframework-devil1.6-cil" installed (on NVidia it is not requred to work)
It looks like it has problem with native SDL:

I think problematic is:
#2 0x009bdf47 in SDL_Delay () from /usr/lib/libSDL-1.2.so.0

If I disenable "libtaoframework-devil1.6-cil" I get error:

I made some tests with computers. I used VirtualBox too. I if the sistem is run on VB I will call it "VB"
I will call my laptop with ATI radeon "ATI", my workstation with Ge-Force 8600GT "GF".

machine OS Virtualbox Option Status:
GF: Ubuntu 9.04: woks fine (se the link)
GF: Ubuntu 9.04: VB ubuntu 9.10, 3D supported: Got the error above
GF: Ubuntu 9.04: VB ubuntu 9.10, 3D NOT supported: Got the error above
GF: Ubuntu 9.10: Haven't tested.
ATI: Ubuntu 9.04: Graphics is very broken. See the link below.
ATI: Ubuntu 9.10: Got the error above.
ATI: Ubuntu 9.10: VB Ubuntu 9.04. 3D supported: Graphics is very broken. (like in the link below)
ATI: Ubuntu 9.10: VB Ubuntu 9.04. 3D NOT supported: Game IS working BUT SLOW!

So if I conclude: on 9.04 it has problems with ati driver showing incorrect, but in 9.10 isnt working at all.

Btw: on ATI and Ubuntu 9.10 other SDL games are working OK!!!
I would like to tell that 3D games are rally working better on 9.10 with radeon (thanks to Mesa 7.6)

TESTING GAME

I am includeing my game and nedded .dll-s

How to test game. You need to have installed:
- libdevil1c2
- libdevil-dev
- libtaoframework-devil1.6-cil
- libtaoframework-opengl2.1-cil
- libtaoframework-sdl1.2-cil

included files that are needed:
-Tao.DevIL
-Tao.openGL
-Tao.SDL

you just run
mono FERI-bomberman.exe
on 9.04 should be working ok (tested on few computers)

Thanks for the report. Unfortunately, the report is very complex and involves code that you are developing. Since you are a developer, please try to pinpoint the problem with a very simple test case that clearly shows that an Ubuntu library is doing something wrong. (Otherwise, the mistake might very well be in your code.) Thanks in advance!

Hello, David,

thanks for your reply! A am not main developer of MonoXNA project and I wasn't programming graphics (i know only very basics of OpenGL).
I done some more testing and all ATI GPU with opensource drivers failed to draw textures correctly, all NVIDIA GPU with proprietary driver works OK.
I can't say much more because I only noticed problem with MonoXNA. Other games/apps/compiz works OK on ATI GPU with opensource drivers.

And, yes, problem is still present in Ubuntu 10.04. I will try to find time to do testing with r300g (Gallium 3D architecture) drivers, and see if it's still present.

Hi Gasper,

I think you have two options:

1) Try to demonstrate the problem in a test application without Mono.XNA (but that might be a lot of work, I don't know).
2) Talk to the Mono.XNA developers to help diagnose your problem.

Either way, I don't think Ubuntu developers will want to spend a lot of time trying to diagnose this, unfortunately. Thanks for your help!

I already talked...I think it's ATI Radeon (opensource) driver issue, but it's present only here. But either cant ATI opensource developers help.

Yes, bug is not concerned with Ubuntu itself. Thanks for help anyway! :)
Bug can be closed as invalid.

Cheers!

Well, I can assign this to the -ati driver in Ubuntu, that's still an Ubuntu bug. What I meant when talking to the Mono.XNA developers was that you should try to pin-point the problem with them.

You have the following layers going on:
1) Your code (non-Ubuntu)
2) Mono.XNA (non-Ubuntu)
3) libtao (Ubuntu)
4) Mono (Ubuntu)
5) OpenGL (Ubuntu)
6) ATI drivers (Ubuntu)

Basically #6 is not going to want to spend a lot of time diagnosing your problem unless you can give them a test case that eliminates some of the layers. Still, if it's an Ubuntu bug, then this report should stay open.

Have you tried testing your game on a different PC with an ATI card?

Hi, David,

thanks for reply.

I tried on at least 3 (different) computers with ATI cards, and all had bug with rendering textures. Right today I was able to test on intel GPU driver (opensource) and it also had same issue.
I tried on at least 4 computers with nVidia (GeForce) cards, and all rendered OK. So I can assume it's driver problem. But I still didn't find any other application that has same bug.
This means it's not driver error, right? But why works fine on all nvidias?

1. My code: irrelevant, it only calls api.
2. MonoXNA: Uses libtao for OpenGL calls. No active developer uses ATI or intel graphics. It may be some bug during reading textures from file, but I am not sure.
http://code.google.com/p/monoxna/issues/detail?id=40
3. Libtao: I will try to find other OpenGL apps.
4. Mono works ok.
5. OpenGL. Radeon driver is OpenGL 1.5 (or less) and does not suppert GLSL. But that's not case. I done some basic OpenGL examples in Tao.OpenGL only basic box with textures...) but worked ok on ati an nvidia.
6. I already send bug report on Radeon, but I could not give other example of issue. (I can't find bug)

I will try some other Tao.OpenGL (mono opengl) applications and report back.

Hi!
I finally managed to find out problem. (Mono)XNA uses S3 texture compression (DXT), which is patented. Open-source drivers (Mesa) can't legally implement it. Status can be set to "won't fix".

OK, thanks for the update.
