[opensuse] Tearing/stepping windows after updating to KDE4.11?
I just bumped up to KDE4.11, and I'm seeing something "new". It's minor, but visually annoying when I notice it. Basically if I move a window left or right, the window redraw steps... a portion of the window is always leading the rest, and the step point.. the tear?... drifts up the window from bottom to top. Once it reaches the top it starts over at the bottom again. It's like a wave flowing upward in the window. glxinfo gives me this: ---------------------------------------------- OpenGL vendor string: NVIDIA Corporation OpenGL renderer string: GeForce GTX 660 Ti/PCIe/SSE2 OpenGL version string: 4.3.0 NVIDIA 319.32 ---------------------------------------------- So, in theory it shouldn't be the video card.... Other info... uname -a Linux linux-s4o5.site 3.7.10-1.16-desktop #1 SMP PREEMPT Fri May 31 20:21:23 UTC 2013 (97c14ba) x86_64 x86_64 x86_64 GNU/Linux cat /proc/cpuinfo vendor_id : AuthenticAMD cpu family : 16 model : 4 model name : AMD Phenom(tm) II X4 965 Processor Any ideas on this one?

Under KDE4.11 I see there are additional items on the Advanced page of Desktop Effects in System Settings. One of them is a choice of OpenGL compositing type; and another is called Tearing Prevention which seems to be new (or at least I don't recall having seen it before). If you haven't tried these already is there something in there that might help, I wonder??? -- Robin K Wellington "Harbour City" New Zealand -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Hmmm interesting. I set it to OpenGL3.1, Native, Only for Shown Windows, Smooth, Automatic, and that combination cleared things up a lot. Now instead of huge jaggies, I get a slight rhombus effect when I drag left/right. That I can deal with. The trick here was the combination of setting OpenGL and Scale method=smooth. Any other Scale method just increases the step pattern (a lot in some cases/combinations). XRender is the worst for jagged step patterns..
