I ‘ve recently purchased an XFX Radeon HD 6850 1GB DDR5 - Black Edition (HD-685X-ZNDC) and I have a problem with slight blurring at desktop (it sometimes appears and becomes more visible on icons… it looks like some liquid is on them).
Slight blurring appears while scrolling pages through the bar, too (doing the same thing slowly with mouse wheel is ok).
Also, flickering appears on most application-windows while resizing them to the left (extending them to the right seems ok), but resizing Catalyst Control Center’s window to the right or resizing the same window while in “Pinned/AMD Home” to up, cause flickering as well.
Despite the above, the system is stable with no crashes and games run fine. I have tested FIFA 12 & Doom III, with full video details, until now.
Temps are fine… 42 to 50 Celcius while idle, 52 to 68 Celcius while gaming.
The running OS is Windows 7 x64 with the latest DX11 and currently installed drivers are AMD Catalyst v11.9…
I have tried all AMD Catalyst drivers that I ‘ve found with no luck (CD drivers, 12.7, 12.6, 12.4, 12.3, 11.9, with or without AMD Application Profiles v12.7).
Furthermore, the following problems occur (but they simply disappear by changing from “Basic and High Contrast Themes” to “Aero Themes” through “Personalize” option):
1.1) window tearing while window resizing and sometimes while moving the window fast
1.2) right click menu items flashing after highlighting
1.3) window content flickering while scrolling page
1.4) task manager:
1.4.1) tabs flashing while highlighting
1.4.2) items flickering while resizing window
1.4.3) cpu load bar flickering (sometimes)
2) CATALYST CONTROL CENTER: picture inside Video/Color tab flickers while scrolling page
Another problem which made Windows Live Messenger to blur and some selection-bars in FIFA 12 to tear was solved by disabling “Morphological filtering”. I have turned off “Enable Surface Format Optimization”, too.
My system’s specification is the following:
Graphics Card: XFX Radeon HD 6850 1GB DDR5 - Black Edition (HD-685X-ZNDC)
Monitor: Samsung SyncMaster 2032BW (LCD)
VGA: 1680x1050@60hz (32 bit color)
Power Supply: L&C DR-8600BTX 600W
MB: ASUS P5K (LGA775)
CPU: Intel Core 2 Duo E8400@ 3.0GHZ
RAM: 4 x Kingston ValueRam DDR2 CL6 2GB = Total 8GB
I have tested both DVI-D and DVI-I ports using DVI cable and DVI-I port using DVI-to-RGB connector + RGB cable with the same results (DVI-D port does not work with RGB).
Also, I tried an HDTV screen (LG M2362D) using the above configuration with no better output, but the screen got more blurry with HDMI connection.
Below is the FurMark’s result after 15 minutes (1st page on the left) and after 1 minute (the rest):
Has anyone experienced something like that? Any recommendations?
Thanks in advance.
P.S. Sorry for the long post, but this issue bothers me for almost 2 weeks now…
