Hi,

Something happened a while ago, back at KDE 4.7; still present with KDE 4.8:



The video card is the same as ever, NVidia 6100; never consciously touched anything.

Have you tried adjusting the Anti-Aliasing setting in System Settings to forcibly enable Anti-Aliasing?

This could have been disabled by a system update - likely to X.

Where exactly? I am aware just of Application Appearance->Fonts->Antialiasing. Fonts are perfectly good, though. It's only visible in places like shown on the pic.

My clock appears as follows - http://i.imgur.com/jVjIs.png

Have you tried causing your clock to be redrawn by changing it's size?

No, I haven't. But then I never touched it right from the beginning, ever. Same video card, same monitor, same everything. BTW, did you have a close look at the window buttons on my pic? They also changed on their own.

Have you tried using a new user account? Also, did my suggestion to change the size of the clock have any impact?

I think this appears because raster graphicsystem. When you use native graphicsystem then widgets are antialiased.

I noticed this almost year ago but I didn't know where to file raster bug (probably at qt bugtracker).

Can anyone confirm that this happens only with raster graphicsystem?

I think if you use raster graphic system, and if you use Llama's theme for the analog clock, then your clock will not be antialiased too. I really think this is raster bug. But I could be wrong

If the issue appears with the raster graphics system, but does not appear with the native graphics system, then it is likely the Qt raster graphics system that is at fault.
