Being the bug submitter on the Debian BTS it looks to me as if this bug is related to bug #4686: https://bugs.freedesktop.org/show_bug.cgi?id=4686 The graphics board is the same and the effect described in the bug fits my observations. Maybe these two bugs should be linked. |

Bug reported today on the Debian BTS by Johannes Tysiak. "When using XVideo in fullscreen mode there are horizontal stripes all over the picture (using a GeForce FX Go 5300 aka NV34GLM). It seems to happen when the overlay picture takes almost the whole screen width and starts on pixel X=0." See the Debian bug for details. The following patch fixes the problem on his board, but it is not clear whether the fix should be enabled on other hardware too. Tested with driver 2.0.2, still applies on top of 2.0.96. --- xserver-xorg-video-nv-2.0.2/src/nv_dac.c 2007-04-14 06:20:28.000000000 +0200 +++ xserver-xorg-video-nv-2.0.2.patched/src/nv_dac.c 2007-05-20 16:23:55.000000000 +0200 @@ -119,6 +119,8 @@ horizStart = horizTotal - 5; horizEnd = horizTotal - 2; horizBlankEnd = horizTotal + 4; + if(pNv->Architecture == NV_ARCH_30) + horizTotal += 2; } pVga->CRTC[0x0] = Set8Bits(horizTotal);
