For some reason my reply to your post was removed. You need to call Applecare about this. I had the exact same problem. In fact one of your linked screen shots it MINE. After Apple replaced my X1900 card the problems went away. Clearly it shows a hardware problem. As I said in the original reply, Leopard pushes a video card harder. I'm betting all the Mac Pros you are referring to have rev1 X1900 cards. You can blast the heat sinks out with compressed air and sometimes the Leopard glitches go away. However they do come back. Basically the RAM on the X1900 is going bad and Leopard triggers it.
Hopefully this reply doesn't get removed...

also fair enough and glad that it is working for you
my frustration and anger over leopard,and I'm a hugefan but also not blind,is that the severity of so many bugs that are in leopard are not ones that are hard to catch
this without a doubt means thatknowingly released a very bug ridden OS without caring much about the repercussions.only sales mattered it looks like,which is true for most businesses except that there is usually a balance between sales and quality.with leopard
seems to have forgotten the quality part and dropped the ball
like the graphics problems that plague most mac pros with x1900s,which is also what most mac using professionals use,the bug isnt hard to track down and notice. in our main office we have 6 mac pros with the radeon x1900s. 6/6 are affected. at home i have a mac pro with x1900 and macbook pro. my mac pro has the same problems. of my friends that have mac pros with the x1900,all i've talked to so far which is at least 10 have the bug showing constantly also.
the bugs with this configuration,again i think probably's top selling pro config make the system unusable for almost anything.like i said there are thousands of similar screenshots on the net but just so you get an idea of what i mean look at

these little lines are shown all over the display,constantly with no way to fix it.the colors and shapes also appear covering up everything on screen under them continuously while using leopard. if it happened just once in a while or was not common and some oddity or rare bug that'd be one thing.But its not. ifput leopard on a mac pro with the most popular graphics card they sell out of the 3 options they offer,they would have seen this bug.
which even fuels my frustration further because there is NO doubt that they saw this major bug and still went ahead and sold the OS at retail and up until right this moment they havent even officially said it exists.
and deleting thousands of posts on their discussion boards to try and silence the issue?? is that reallly a company that should be given all of your 101% trust? come on people wake up.Apple isnt perfect,far from it in fact. and with all of their recent problems it appears that as a whole the level of quality atis falling like a stone.
those of you that respond to those of us that 'dare' to speak against the almighty and say that we're just whining,you are the ones that are going to get screwed at some point ifdoesnt clean up their act.like i also said its nice that your install works perfectly,but don't deny that other huge issues dont exist.that is just flat out irresponsible and shows a bit of brainwashing from
