Horizontal black lines across screen when panning
 

System: Fedora 16
Installed: some 32 bit libraries I found necessary to get the games working
alsa-pulseaudio backend


I have run into this alot lately. I have intel hd integrated graphics and whenever i play flash / adobe air games I get random horizontal black lines almost like flickering on the screen or some background image pops through the foreground. This only happens when the screen is panning.This does not happen when on websites only running games locally

List of games with the issue:
What Makes you Tick : A stitch in time
The Clockwork Man
The Clockwork Man 2

A little more info:
I'm using 64 bit linux but many of the games are 32 bit only
I also have no problem with some other 2d games like super meatboy or Sword and Sworcery.


I also noticed that many games run very slowly. Are the intel HD graphics really that bad on linux?

The question is: Am I missing some sort of 32 bit library for these games? Or a driver of some sort? How can I get rid of the black lines going across the screen when panning?

Horizontal black lines (about 20mm wide) are usually a sign of frame synch slipping. The 'frame' is the vertical synchronisation, to prevent the picture rolling up and down.

In a word, yes. You can cycle through the video drivers and try for the one that works best. Have you a 32 bit mesa/driver setup? It may help

Probably. test with 'ldd /path/to/executable |grep found' Anything shown is a problem. You can also drop the '|grep found' and check that it's not pulling in libs from crazy places.

Also, try panning slower, Throughput is probably a problem. A game running on 320x200 would do better than one on 1024x768.
