Week-old install, openSUSE 13.1 with updates, KDE4.11.5, on a laptop with quad-core AMD with integrated "discrete class" Radeon graphics, 4 gig RAM.
Fresh boot, it's fine, but gradually the response of KDE slows down. Apps do not slow, open browser for instance is fine. Heck, even a heavyweight app like VirtualBox is fine. Animation if I close an app is snappy, and it makes no difference if desktop effects are disabled. System monitor plasmoid shows plenty (say 50%) of RAM and CPU available. Process seems independent of load; problem happened tonight under no load at all: Booted, dined, returned to find computer unusable.
When I say KDE is slow, I mean that if I move the mouse down to the bottom of the screen, the taskbar takes minutes to unhide. Then when I click on the menu launcher, it takes minutes to open, though it may show an outline for half of that time. Then when I click on Leave, more minutes, then when I click on Restart, more minutes 'til the confirminator pops up, then when I click on that, more minutes. Yes, 15min to shut down. Right-click menu takes just as long to respond. Key bindings take forever, too.
If it were always slow, I might suspect graphics driver issues. If it slowed more when I used more apps, I'd suspect memory management issues, but getting slower over time even under minimal load, has me confused. Typical usage case is browser-based research pertaining to my new install, just some google searches and reading forum posts, and then when I go to implement whatever I read about, I can't get the menu to open!
My research on this problem points to a lot of folks complaining about slow KDE, in older versions a few years ago (when it was working fine for me on an older computer, also with Radeon), and people telling them not to use any cool features of KDE if they want it to be faster, but not so much on the fast-at-first-but-gradually-slowing issue. Is anyone here familiar with it?
Thanks,
