unable to handle PNGs

[dreadkopp]

Aloha Community,

 

i run 10.9.2 with 10.9.0 system/sandbox rollback on my AMD build (Asus m4a88t-m, phenom II X4 945 undervolted @ 1,2V@3,3 ghz, Nvidia 460 gtx SE @ 900 mhz)

 

It's nearly perfect. Got PoweerManagement to work for the Nvidia. All Hardware is working well (no PowerManagement or AMD yet... but since i Undervolted the CPU its still col and quiet)

 

the problem is that i can't handle PNGs.

 

when i try to take a screenshot i got an write-error.

 

when i try to set a new icon to a app it's not possible, either it doesn't even save the picture or it turns out red/pink.

 

tried various kernels. bsa_kernel v9 is not working for me. boot stops aufter graphics card arrived.

 

i had a install running before, which hasn't got this problem. then i was making a usb installer with 10.9.0 from appstore and pandora app and updateted to 10.9.2 later.

 

this time i first tried pandora which led to the problems. i tried myhack later, but still the problem.

 

the original Installation becomes corrupt due to too much messing with kexts i think.

 

console throws something like : "ImageIO kxImage Invalid Parameter"

 

I hope someone could help me figure out what the problem is.

 

greetings!

Sorry, I don't have a solution. Just wanted to confirm that I have the same issue on the latest Sinetek kernel. I think it's a problem that affects the pre-Bulldozer CPUs which don't support some of the newer instruction sets. I don't think there's much that can be done, unless one of our brilliant kernel devs can figure it out. 

 

One thing that I think helped the issue a little was using Chameleon Wizard to update to the lastest version of the Chameleon bootloader. I don't know why that would make a difference, but before I had the version from myHack and it wouldn't let me save large screenshots (like my entire desktop). After updating the bootloader, I can now reliably take a screenshot of my whole desktop.

what buggs me is the point that i got it running without this problem before. what kernel and bootlflags do you use?

[phantomsniper773]

• USBLegacyOff=Yes
• npci=0x3000
• GraphicsEnabler=No

My kernel is taken from Sinetek's GitHub repo compiled by Gordio from here.

I suggest you stay with 10.9 or 10.9.1: there's no sense updating to a deeply hacked system and expecting it to be anywhere near stable.

[dreadkopp]

i would if i could. but the download from appstore is 10.9.2. also i haven't had this problem before with update to 10.9.2

[phantomsniper773]

Oh really? I'm on 10.9.0 and I still have the problem. Weird.

[dreadkopp]

tried a fresh 10.9.0 install and various kernels (cannot get anv baa_kernel r9 to run)

 

i can either not take a screenshot at all (write error it says) or they turn out pink.

 

it's not just screenshot, it's everything which needs to handle pngs.
