I'm pretty lucky. I have two issues, Open GL errors, AND artefacts not rendering (see pic below). I've had both for awhile...since 2012. I have an Asus G73JW series and it worked like a charm for the first year and a half...2011 and part of 2012. Luckily I have a pc, so I've just been using it for SL, but now i've moved to a smaller place for the summer, and would like to be able to use my laptop. So I"m trying yet again to fix these issues! I just spent $135 bucks getting my system restored along with the Tech guy trying to fix the issue. He played with the settings, increased the TDR, installed old card drivers from 2011 (prior to when I started getting these issues) I can't say how much of my own time I have spent trying to fix them. I've done a clean install of graphic drivers, played with the settings, hired someone, increased TDR, tried 3 different viewers, researched, installed ASUS Gamer OSD and uninstalled it, system restored the laptop, prayed, cursed and almost threw the laptop against the wall! (that's still an option) If anyone has any ideas on how to fix these issues, let me know. I have an Asus G73JW Grid: Second Life Built with MSVC version 1600 CPU: Intel(R) Core(TM) i7 CPU Q 740 @ 1.73GHz (1729.05 MHz) Memory: 8117 MB OS Version: Microsoft Windows 7 64-bit Service Pack 1 (Build 7601) Graphics Card Vendor: NVIDIA Corporation Graphics Card: GeForce GTX 460M/PCI/SSE2 Windows Graphics Driver Version: 8.17.0012.5912 OpenGL Version: 4.0.0 Viewer SSE Version: SSE2 libcurl Version: libcurl/7.21.1 OpenSSL/1.0.0g zlib/1.2.5 c-ares/1.7.1 J2C Decoder Version: OpenJPEG: 1.5.2 Audio Driver Version: (none) Qt Webkit Version: 4.7.1 (version number hard-coded) I finally submitted a bug issue, but i"m not holding my breath. This is what I see when I"m logged in...it doesn't matter the viewer or the graphic setting. I can change the graphic setting and this will disappear for a bit, then start again. Or zoom out and it will fix it. And it's not a hardware issue. It only happens in SL and all the pop up windows in SL look fine. My desktop looks fine, it's just contained within SL.
