Hi Guillem, thanks for your report. I can confirm your issue because I can reproduce it on my Lenovo X200 laptop with an Mobile Intel GM45 Express Chipset too. However the game works fine on my computer with a Geforce 9600 GT (nouveau drivers) and another one with an AMD HD 6450 video card (radeon drivers). The author of foobillardplus is aware of the problem. He has already mentioned it in his README file. Unfortunately I installed the file into the wrong package (foobillard), so it was easy to miss. I'm aware of this mishap and I will install the README to foobillardplus with the next revision. The Tessellation errors don't seem to be related because they also appear here on my computer where foobillardplus works flawlessly. This might be a different problem but at the moment I consider this output simply as noise. I have the same suspicion as you that the Intel GM45 chipset is not capable of rendering all graphics because of missing OpenGL extensions. I'm not sure yet whether this is a sole hardware problem or a driver issue. Though Foobillardplus requires 100% OpenGL compatible graphic card drivers. I'm inclined to clone this bug report and to reassign the clone to xserver-xorg-video-intel. If the maintainers of the intel driver confirm that this is rather a hardware issue than a driver issue, then this bug should be marked as "wontfix". If it is a driver issue, then I intend to keep this bug report open until a open source driver is developed that fixes the issue. I'm not so sure about the "software fallback code". In most circumstances this means that users experience a very sluggish game and in my opinion this isn't a real fix. So in short: I believe this is an issue related to your video card and it won't/can't be really fixed by the author of foobillardplus. Regards, Markus
