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).

Ingo

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