Hello, Andre: Earlier, I provided my xorg configuration and Xorg.0.log (they were not addressed to you, but you can find them on the bug's page). They may help you to set up an environment. There is no colour depth specified in my xorg configuration, so it's whatever it defaults to -- I guess 24?

Hi Arren, The SSE2 code is really faster than C equivalent, but performs better with images larger than 16 pixels wide. Since to get the SSE2 best performance we need to align the destination address in 16 bytes. So all operations are made in three loops, one for the alignment, one for the bulk op

Sorry, I left out this piece of possibly useful information: I have a dual-monitor setup -- one is 1280x1024 and one is 1680x1050. I usually run konsole maximized across the larger monitor, and it is terribly slow like that. When I make the konsole window smaller, the problem becomes less noticeab

Hi Arren, This is a old patch, about add SSE2 implementation for many compose operations. This code was first released in pixman 0.12.0. I really don't know what is going on, I need to investigate this. Just in case, a good test is run the pixman configure with --disable-sse2, to disable this cod
