Man, that sucks.
Have you experimented with the graphic's resolution etc. - to see if there's a certain point it goes tits-up. If other people are reporting their Pros are behaving (and they have the same setup as you) it must be something particular with your setup. As you say, 6 out of 6 hardware malfunctions is not going to happen.
i've seen some posts that said they get less problems when running under their monitor's top resolution. a few people with 23 inch cinema displays [like me] said that they get less artifacts at lower than max resolutions like 1600x1200,not that these machines even stuttered before in tiger at the max resolution,but there's something weird going on obviously
i tried that on my home mac pro and there does seem to be less artifacts and lines but they do still appear.also have tried disabling quartz extreme but it has no noticeable effect. it really sucks because even for those that a lower resolution works [better], 1600x1200 or lower is a big step down from something like 1920x1200 [max on 23 inch cinema displays and similar monitors. though it is reported to happen on any size monitor i only have experience with 23, 20, and 26 inch ones and it effects all of them the same]
like many of the other bugs in leopard and everything else they make,they are SO slow to officially 'recognize' even gigantic flaws. there are tons of reports of people bringing in their mac pros,having the apple store send them out to get a new x1900,waiting 3 or more days and then taking it home all to realize that the problem hasnt changed. being so widely reported and since it is obviously a pretty big issue on the major leopard bug scale, keeping mum and not even saying the problem exists must be costing
a bundle. doesnt make sense. who knows maybe the silence as usual has been calculated to to not cost as much long term as admitting huge design and QA flaws outright? i have not a clue
what i do know is that the problem is real and if the entire Apple Inc. doesnt have more than 3 or 4 mac pros that they have tested on,they are nuts. since this is almost surely not the case and they almost certainly DID have more than a few mac pros in this configuration [again the most popular mac pro they sell by far] and are still not acknowledging this flaw,things at the old
are slipping far too fast and drastic.
in all my years using Macs,i have never seen this amount of sheer dissatisfaction and bad design,implementation,& testing as has been shown with leopard and the company as a whole over the past year or so.
not to mention the utter disrespect and outright disregard for their customers by erasing the majority of posts on their message boards that point out problems or bugs, or even simple questions by truly confused people that are stuck [like 'i installed leopard and my hard drive wont mount. can someone please help?'-----posts similar to that and anything that may point out a trouble spot in leopard are just deleted]
that is NOT a very truthful or helpful way of dealing with issues that people may be having with a product they have spend thousands of dollars on
the earlier comments on here about leopard being 'Apple's Vista' have been shot down all too fast by most people on here i think.
in many ways it is really the reality that
managed to get themselves into and they should be held responsible for handling things as they have recently. YES all software has bugs and YES many people are using leopard without problems. BUT there are also TONS of users that have been stunned by leopard and
's apparent lack of progress over the past 2 years. there are some great ideas that have not been even close to fully implemented [look at the WWDC leopard samples of Stacks for example] and instead of following their usually dead-on experience with usability they decided to put marketing over---FAR OVER-----the actual needs of the majority of customers. and it is stinking more everyday.
