Looks like you don't have a working font link for Tahoma.
Because my another subpixel rendering setting. See the updated test program, and result image.
The resulting image confirms that your Tahoma font link is broken.
My Tahoma font linking setting is [Software\Microsoft\Windows NT\CurrentVersion\FontLink\SystemLink] 1228979629 "Tahoma"=str(7):"gulim.ttc,Gulim\0simsun.ttc,SimSun\0mingliu.ttc,PMingLiU\0msgothic.ttc,MS UI Gothic\0" This is the same with MS Windows Tahoma font linking setting.
Do you have those fonts installed?
