Does anyone know if the workarounds are still needed or if that was a fixed bug? I read the changelog but was unable to discern whether or not these were on the list of fixed kwin bugs.

Still needed; has not been confirmed to be fixed: "Fix regression which caused desktop effects not working with some drivers. Fixes bug 243991. See SVN commit 1167908." [1] "very likely. there's a massive amount of "similar" problem reports (freezes - press shift+alt+f12 - or fragmented screes depending on the resolution, latter one just like this on your particular GPU, see the other two dupes and bug #241402, while it's not clear that latter one is really related)" [2] "I just did a commit, but I do not know if it fixed it. I have to properly investigate the issue but currently I am lacking the time. If I get a patch before the release I will send a notice to the release team."

Try this Denis: [msx@paradise ~]$ cat /usr/share/autostart/plasma-desktop.desktop [Desktop Entry] Exec=plasma-desktop --graphicssystem raster Also you can add --graphicssystem raster to all KDE apps to boost performance, specially Yakuake if you use it. This hack should work with KWin composite feature enabled. -Martín "Un buen antivirus, no debería dejar cargar Windows y sugerir instalar GNU/Linux xD" - omar_uy@#parabola@freenode

Well, composite didn't work with raster graphics system. But the old one is fine. I'll continue looking for other options too. Thanks for the hint!

In fact, the vsync option was re-enabled. After I turned it off, the performance was restored to the levels of 4.5.0. I think It could be better, but it is fine now. -- A: Because it obfuscates the reading. Q: Why is top posting so bad? ------------------------------------------- Denis A.
