Point 1. The clock on your system is wrong and your mail is showing arriving in the future.

Point 2. I have never ever seen such a bug. I'm not saying it's not Manta's fault, but Manta has been run on many different systems without showing this problem. You are running a likely very new version of the X server with never before used drivers.

The most likely scenario is that we are doing something the X server isn't expecting.

One thing to try is to build a SSE disabled build. You can do this by turning off MANTA_SSE and MANTA_SSE_GCC. See if that fixes the problem.

hi all,

just compiled manta on my new t61, and noticed something that looks like a bug (both gcc and icc, release mode): the displayed image is not correctly aligned inside the frame of the "parent" window, but somewhat "shifted" to the left.
On the left side, pixels appear "outside" the frame (in the background, actually, where they remain if you move the frame !?), while on the right, a few pixels are left un-initialized. The number of wrong pixel-rows depends on the window pos, looks somewhat like if the window goes from x0 to x1 then the written pixels start at "lowestmultipleof8(x0)", and go 'til "lowestmulitpleof32(x1)" (8 and 32 are guesses only, it's hard to tell).

PS:
Could also be a bug in the x-server -- it behaves a bit strangely after I tried to run some cuda stuff....

hope that helps finding it ...
