Intel graphics drivers - Aug 2017

[Charles Pegge]

I noticed recently that many of my opengl examples no longer fitted onto the window. This appears to be a problem with the 23 Aug 2017 Intel Graphics driver, and possibly earlier drivers. My HP laptop (windows 10) automatically updates itself for both Windows and HP drivers, so I can't be sure.

If you have one of the newer laptops, you may be in the same predicament.

I hope this problem goes away with the next driver release.

My findings are posted here:

Are you downloading the graphic driver from Microsoft or Intel?  If from Microsoft, try downloading it from Intel and see if it is any better?

I am on Windows 10 and have an Intel GPU, but my system has never had an update.

I'm fairly sure it was from Intel  via an HP driver update, since my laptop is an HP Pavilion. I have never seen this over-sizing behaviour until now.

After ruling out any o2 bugs in my development version, I came across this bug report on the Intel forum, relating to Minecraft. Google is really good at semantics when it comes to researching problems.

I have never seen windowed issues like this, usually issues like this are full screen and are because of using an unsupported resolution or bit depth or non power of 2 images.  Power of 2 is a non issue nowadays as anything gets automagically scaled to the next highest power of 2 and unsupported resolutions should not be an issue for windowed screens.

I would roll back the driver if you could.  GPU drivers are pretty finicky.  I personally never update one, if it is working properly and I am happy with the performance.  About the only time I update a new GPU driver is if support is added for something I really need like a new video codec.

Problem aside, the screenshot looks interesting.  What are you making?

By chance are your DPI settings 100%? or are you using high settings, like 125% or 150%?  If so, those can really skew the SystemMetrics if you are not building your program DPI aware.

Not saying this is it, just scratching my brain and trying to think of a possible issue that could cause this...  Most likely is just a gooched driver as your coding is second to none.

Hi Kuron,

I am using the default settings for just about everything on this laptop. My retired vista/nvidia PC runs the opengls perfectly, as did the laptop until the last month. So the safest thing to do is wait for the next driver to arrive. Reconfguring my laptop would be of no benefit to anyone else.

That demo is: examples/opengl/controlPanelsOverlap.o2bas, and demonstrates GUI panel stacking, with correct z-ordering for translucent objects when they are brought to the front. Making a 3d GUI framework is one of my long-term projects.
