I've seen the exact same problems on my Intel 4600 on Windows 10. We've seen the problem on pretty much every Intel 4000+ card tested on every version of Windows for the last couple of years. Most of our Linux machines with Intel also have Optimus, and we disable the Intel side through BIOS, so I don't have any useful Linux input. I finally tracked down a fix, and I think it suggests a bug in the Intel drivers. The problem appears to be due to issues with the textures that are loaded from glTexSubImage2D in Glyph.cpp. The following patch worked well for us and fixed the disappearing text glyphs problem on Intel. It works by reapplying the texture min filter right before the glTexSubImage2D(). Without this, depending on the size of the font, glyphs that are loaded after the initial set will show up either grey, or completely transparent. NVidia drivers do not suffer the same problem. I've tested on Intel 4600 and NVidia K2100m. I've also tested the state values with glGetTexParameteriv(), and it appears correct prior to this code. That implies to me that this is a driver bug, but I don't have enough experience to say for certain. If it is a driver bug, it's been outstanding for at least a year, if not several years. I could not find a way to fix this in our own code without modifying OSG code. I hope someone finds this useful. I realize it is a bit of a hack.

Re: [osg-users] StatsHandler missing numbers
Hi, I stumbled across the same issue and i found the trigger for this issue. The font resolution is the trigger for this issue. I did some testing and found that: - using 64 the text disappears completely - using 32 (the default) results in some missing or wrongfully colored characters - using 16 the text remains visible and in the correct color >From my testing i could see that increasing the font resolution also increase >the render issues as well (up to the point were no text is visible anymore). Note: This issue only occurs on Intel GPU (with the latest driver installed). I've only tested on Windows machines so far and this issue might be limited to Windows, but i'm not sure.

Re: [osg-users] StatsHandler missing numbers
One major problem with the Intel drivers is that their products are typically EOL'ed (end-of-lifed) three years after first release - at which point they stop receiving driver updates (not even bug fixes). You can see the problem with the integrated graphics in Intel's Sandy Bridge chips (introduced Q1 2011). You cannot get any OpenGL drivers dated newer than April 2014 - and some OpenGL features we require simply aren't working with this driver release. And so we have to tell some of our customers that their laptops have use Ivy Bridge or later microarchitecture - or be equipped with a separate dedicated graphics chip.

Re: [osg-users] StatsHandler missing numbers
Hi Andreas, What release of Intel drivers are you running? I recently experienced issues with an application on various Dell notebooks and Intel NUC barebones (all HD4000-based) where texts printed with glRasterPos3 were not displayed at all with driver release 8.x. Upgrading to release 9.x (from Dell and Intel websites) solved the issue. I didn't found anything clear w.r.t. this problem in the Intel drivers changelogs though. It's noteworthy that the application I was referring to isn't OSG-related (plain OpenGL) and was running on Windows 7 (not 8.1), but who knows!

If I try making a screenshot, the screenshot is totally fine. You must think that I'm crazy... If I press s for the stats in fullscreen the cow modell is shown normally =). In fullscreens they are drawn in a bright gray color. In window mode you only see the zeros, the others are missing or to bright. I must have the newest drivers, but I look at them. ... Thank you!

Re: [osg-users] StatsHandler missing numbers
Hi Andreas, I have pretty new Intel board on my laptop and got into few problems with the StatsHandler - just accidentally I changed the threading model of the Viewer and I got it back to normal. This is a hint no clue why it is happening but maybe worth of try cheers, Nick On Fri, Apr 17, 2015 at 3:31 PM, Christian Buchner christian.buch...@gmail.com wrote: One major problem with the Intel drivers is that their products are typically EOL'ed (end-of-lifed) three years after first release - at which point they stop receiving driver updates (not even bug fixes).

Re: [osg-users] StatsHandler missing numbers
Hi, thx for the hint, sometimes they help ;). On my laptop it did not work, I tried every Threadmodel I could find in the viewer. No changes. But i realized that this error in fullscreen is just the lower 2/3 screen. In the top 1/3 the object are fine. I tried to update my driver, but intel driver update said there are no new ones. Just for my wlan...Telling me to download it and then saying oh you got 64 bit, sry it works only on 32 -.-... But thx to all the answers you posted ;) ... Thank you!

[osg-users] StatsHandler missing numbers
Hi, if this was asked before, sorry for the repost I searched for it, but did not found something. My problem is the following: I want to read a few information from my scene. I use the osg statshandler where I can press s and get the frame rate and so on. This works but has one error. A few of the numbers are not show. Example, the x is not shown and the 0 are flimmering: Frame Rate: x0.00 Vertices: x Triangles: x My graphic card is an Intel HD Graphics 4000, can this be the cause of the problem? ... Thank you!

Re: [osg-users] StatsHandler missing numbers
Hi Andreas, I haven't heard of problems in the form your are describing before. There bugs in Intel drivers so it could the issue here. What OS are you using? Does osgtext run OK? What version of the OSG are using? Could you post a screenshot?

Re: [osg-users] StatsHandler missing numbers
Hi Andreas, Thanks for the screenshot. I see that there are missing characters, which is odd, and might be a hint to the cause of the problem. My best guesses right now are a memory issue or a driver issue. What happens when you run something like: osgviewer cow.osg And then bring up the stats? Robert.
