Description David Johnson 2008-07-14 01:10:06 UTC

Version:            (using Devel)
Installed from:    Compiled sources
Compiler:          gcc 4.2.1 
OS:                FreeBSD

The folderview is not rendering correctly. I am unsure how it is supposed to look, but it displaying other areas of the screen, almost like a window with no fill. I am attaching a screenshot. Border handle does appear to work, and if there are icons in the directory, that can be seen (though sometimes obscured).

almost certainly a graphics driver issue. are you using kwin's desktop effects?

Comment 3 David Johnson 2008-07-14 06:59:00 UTC

No desktop effects. My video card is Radeon 9000, using Open Source "radeon" driver.

I have figured it out though. Through semi-random changing of driver options, I have discovered that I need to set AccelMethod to EXA (the default is XAA). The folderview now renders correctly (although rendering performance does not seem to have been improved). This option is marked as possibly unstable in the man page. It also causes KDE3 kuickshow to render garbage.

As this driver is somewhat common, this may be a candidate entry for a FAQ.

Comment 4 Aaron J. Seigo 2008-07-14 09:31:37 UTC

upstream driver issues, then. and yes, i'll see about getting this added to an faq.

Aaron, David: if no one else does it by the time I get back from work, I'll see about adding this to the Plasma FAQ.

Done.  You can find it at

Feel free to improve on it.
