When I start the game it goes fine but the screen is all 'flickery'. There are black triangles and stripes flickering erraticaly on the screen. When ignoring the flickering the scene looks like it's rendered fine!

I have tryed putting all settings to minimum and maximum (also window mode) but all is the same. It's not monitor flicker (it's a TFT screen) but still maybe it's vsync, but I don't know where to turn it on or off.

I have Centrino laptop with integrated graphics using PCLinuxOS.

isyour desktop running in 16 bit mode?

In my experience this usually indicates an overheating video card, but that's unusual for a laptop. Could be a driver issue too.

What do the first few lines of your ~/.vendetta/openglinfo.log say (I don't need the long list of extensions, just the renderer and the version)

I can duplicate this problem on Ubuntu Feisty with Nvidia Go 6800 Ultra, but it is caused for me by an incompatibility with Beryl. Switching to Metacity before playing eliminates the issue.

Are you running any compositing window managers? Beryl, Compiz or Compiz Fusion? If so turn them off and see if the issue remains.

i also get this issue but it is isolated to running vendetta in another xsession and switching to and from this session:
startx ~/bin/vendetta -- :1
this seems to be repeatable on more than one distro since i have heard reports of gentoo having similar issues

This problem exhibits itself for me as flickering of the models shown on the main screen, the Stations screens and often while leaving through the transparent field during station exit. The flickering problem occurs off and on, about 3 - 10 seconds, and appears to be on one frame, off the next. Transparent layers seem to trigger it more. When rotating a ship in the purchase view, I can turn it so that a part of the ship is close to the view. This part of the ship appears to escape some sort of plane, and is unaffected by the flicker.

This is the only program to exhibit such behaviour.

Thank you, and I hope this helps.

I don't suppose you're running from inside xgl?
