0.12.1 problems for Windows 8

[Phongsathon Kitchawet]

For me, Stellarium 0.12.1 worked very well for Windows 7 (32-bit).
But when I used Windows 8 (32-bit), I found some problems:
1. There was a black dotted line 15 degree above the horizon.
2. Stellarium worked very slowly, much more slower than in Windows 7.
3. There was a triangle around the Sun, stars, etc.
It looked like 4 Sun, 4 Vega, etc. in the sky.

Please see the screenshot that I attached here.

My specification:
Windows 8 Pro 32-bit
Processor: Intel Pentium Dual T2390
RAM: 3 GB
Graphics: Mobile Intel 965 Express Chipset
The graphics card driver is the latest version 8.15.10.2697.

I used Stellarium very often.
Can you help me, please?
Thanks. :)

You need install drivers for graphics card from intel.com website

Dear Alexander,

I followed your advice to download and install the driver from intel.com.
And I found the answer.

1. My graphics card is old (launched 2007).
So Intel no longer supports my graphics card since February 25, 2013.

2. No driver for Windows 8

3. So I had to install the driver for Windows 7 instead.
Before this, The driver that Windows 8 installed automatically was version 8.15.10.2697.
I couldn't find this version in Intel.com website, but other website.
It sounds strange.
I found only the latest version 8.15.10.1930.

4. After installation (overwrite) and restart, now Stellarium works well as Windows 7.
There is no line or triangle. And it works fast.

Please see the screenshot in the attached file.

Thank you very much. :)

There is no triangle for Vega anymore.
