Luckily, you can easily upgrade the graphics driver running on Debian stable to the testing version and leave the rest of your system on stable.

The older driver doesn’t support Intel’s most recent graphics cards and you’ll either have a non-functioning graphics driver or serious performance problems. If you’re on the Debian stable release, you’re currently using the more-than-a-year-old 2.21.15 driver. The Debian GNU/Linux project recently migrated the Intel graphics drivers version 2.99.917 into their testing release channel.

Let’s stay comfortable and get the newer drivers anyway. Debian stable is safe and comfortable, but Debian testing has got better performing Intel graphics drivers.
