igfxsrvc.exe using 10 GB memory, igfxext.exe using 1 GB. v8.15.10.2696. Memory leak?

[eeuge3]

Hello, on my ThinkPad W520 [with Intel HD Graphics 3000 / Intel Core i7 2820QM] I have installed latest (8.15.10.2696) version of intel gpu driver on Windows 7 x64 and after less than 2 days of running of these processes (2 days ago i killed them because of same high memory usage) they are again together consuming 11 GB of private bytes memory, still rising:

status with igfx*.exe processes running:

status right after i killed them:

what is the solution, to delete both exe files?

(when i kill them, they are started again in a minute)

please fix!
