That's exactly what I have on Ubuntu 10.10 with Intel graphics card. Here are the screenshots:

Looks to me like corrupted video memory.

Try reverting back to 0.9.12 and tell us if the problem still occurs. I suspect graphics card driver updates, since there were no significant changes in 0.9.13 apart from removing some redundant switching in opengl.

I suppose if a graphics card driver is badly written, that might have an impact, even though it makes no sense...

So. Yeah. Would be good to know. That's my only theory right now though.

Is it like the screen is "blinking" (objects appear and disappear in factors of seconds)? If yes, therefore I'm having the problem as well. I'm on gentoo AMD64, I got radeon 4850 with open ati drivers.

No, the screen doesn't blink. To be more precise, I saw it blinking, but on a different machine, with ATI Radeon Xpress 200M, but it was because of KMS setting for radeon driver. I fixed it as follows:

# echo "options radeon modeset=0" > /etc/modprobe.d/radeon.conf

In this case, the picture is pretty stable Nemo, I'll try 0.9.12 and tell you about the results.

In my case, sometimes the screen "blinks" (showing the other screen of hedgewars when the game is running), but is random that blink.

I have the following issue: http://www.hedgewars.org/node/1991 when I compile Hedgewars 0.9.12, but I have resolved with the solution of that thread.

So, I tested Hedgewars 0.9.12 and I don't have that issue. But, I don't know if it's working fine or doesn't happen anything because I tested it two times only. And, as Hedgewars 0.9.12 doesn't have TrophyRace (and in this gamemode always have that issue) i don't know if it's working fine.

phyro, how about the ropes map in 0.9.12? does it have the problem?

No.

PD: I miss 003_RCPlane practise.

I made a patch against 0.9.14.1 for RedW that disables a basic optimisation that went in between 0.9.13 and 0.9.14 -
basically it just skipped a bunch of repeated resets of 2D state.

Removing this should slow down any sane card without any other result, but he says it helped his.

So. People here might want to give it a shot

I've just tried 0.9.12 from getdeb - and the result is the same, see screenshot:

So I think it's a generic some problem with graphics/textures on Intel video card.
lspci gives me this:

It seems that number of hedgehogs matters. The more of them in game, the worse the textures are.
Sometimes decreasing "Quality" slider helps, but not always

I saved the file in hedgewars-0.9.14.1/ . Then, I do "make clean", and "patch -p1 < deoptimise.diff" in the folder hedgewars-0.9.14.1/ . Then, I compile hedgewars-0.9.14.1, run TrophyRace, and I still have that issue.

Yeah, I wasn't expecting it to help you, since you had problems in 0.9.13 too.

We could try digging through the revision history between 0.9.12 and 0.9.13 I guess for opengl changes, or you could try bisecting.

Nemo, it won't help. I've tried 0.9.12 and the problem it still there. It's a problem with video card/drivers in linux, I believe.

BTW, if anyone is using radeon instead of fglrx out of some basic sense of principles and not due to ATI desupporting old hardware, you might want to bend your convictions a bit.

Or I guess change your card...

definitely change your card...

the newer cards have much less bugs.

Guys, guys, both me and topicstarter have problems with Intel cards

In Windows 7 (64 bits) doesn't have that issue. Furthermore, in Kubuntu 10.10 (64 bits) I have the same problem (like into Gentoo installation). And always happen in maze maps (like TrophyRace) and in a randomize way in other maps.

Probably happens on large maps.
And, yes, would not surprise me the driver is at fault.

I'm using ubuntu 10.10 and i'm having same problem, also sometimes others characters nicknames are messed using my nickname or same color of my team.

I hate that intel is not full compatible i hope theres a fix for this soon..
i have been thinking...(that maybe if i change the language from spanish to english may solve the problem) id try that:P

punkmexic, one other thought is that possibly you should consider filing a bug on bugs.freedesktop.org against the mesa intel driver.

Obviously if you can help us with that regression range, that would still help a lot.

This doesn't occur with an ati radeon hd 5870 on kubuntu 10.10 x64
