I have been playing about with Conky and have run into an issue.
For those items that vary can frequently, such as minutes and seconds in "uptime," CPU usage, and the like, text renders properly upon Conky startup, but becomes blurred. The best way I can describe it is that it appears that new numbers do not replace old one, but, instead, overlay them, so that the particular column eventually becomes a blurry rectangle.
I have seen this on three computers under KDE and E17. On the same computers, when I use a window manager, such as Fluxbox, the problem does not occur. I've gotten the same results on Slackware --Current, Debian Wheezy, and Mageia 3.
I have tried several edits that supposedly sharpen text, according to the sites where I found them, with no luck. Here's a bit of my conkyrc file that shows some of the items I've tried and then remarked out; I also tried disabling "xftfont" option with no change.
# double_buffer yes
# own_window no
# outlines and borders
# own_window_type normal
xftfont Bitstream Vera Sans:size=10
This screenshot illustrates the effect.
What am I overlooking?
