Good day,

Before I try contacting Hans or A-Eon, I thought I'd ask if anyone else using a HD 4xxx graphics card had this particular problem. It seems to be an old problem that had once occurred with the X1xxx series of cards before RadeonHD 0.32. From the HDRLab page...

Quote:
•Fixed a number of R500 (Radeon X1000 series) compositing bugs that caused various things to be rendered incorrectly (e.g., the intermittent dark/black separators and backgrounds in AmiDock);


With compositing on, white vertical lines appear in Amidock. When Amidock is set to use borders, the lines are thick. Without borders, the lines are thin. (I'll see about posting an image tonight). The lines do not appear at all when compositing is turned off.

So, do any of you HD 4xxx owners have this problem?

Yes I have exactly the same thing, probably a new bug!

@PhantomInterrogative

I have vaguely similar issue which may or may not be related.

I have an old Redoen 8500 LE in my A1XE so have to switch off compositing under 4.1.
However, even with it off I have some graphical artefacts, such as in menu icons and the icons in Codebench.

Might be something totally different right enough.

8500 was never well supported under OS4. Try do get a 9000/9200/9250 and put the 8500 in the Pegasos if it doesn't have one already, the 8500 seems to be better supported under MorphOS.

@djrikki

Once your phone conversation is over, could you please tell me what you did to eliminate the vertical white bars?

Thank you in advance.

This is a known problem with the Sam460 and Radeon HD combination.

So far nobody has managed to track down and fix the root cause. No, it's not a driver issue. The white stripes really exist in AmiDock's alpha mask. It appears to be a weird corner case of copying data to/from VRAM; possibly to do with reads/writes that aren't 32-bit aligned (an alpha mask is 8-bit). Basically, a small vertical strip of the alpha mask ends up with incorrect values. Only AmiDock appears to be affected though, and nobody has figured out what AmiDock is doing that's "special."

Increase the Icon Scale factor 1% at a time until they disappear.

@Hans & djrikki

Thank you for the replies. I'll try the 1% trick tonight.

I don't have this issue with my Sam460ex and RadeonHD gfxs (6670 & 6570)

My Peg1 has a Voodoo 3 in it.
Do you think that would work better in the A1?

I've always had this with my Radeon HD 5450.

I think that changing the position of the icons in the dock can make the lines go away .

I use to "put" one (or more) "Spacer.docky" where the lines are... Then they dissapear.

@djrikki

The 1% scale factor trick works! At 100%, the lines exist. Adjust it to 99% or 101% and they disappear.

Once again, thank you for the help.

@Robert

The Voodoo 3 is at least fully supported although you still won't be able to use compositing because it simply is supported in the hardware. The 8500 should be nice under MorphOS too, full 3D support etc.

I found your posts sligthly confusing but I think I now have them worked out. Emphasis mine.

I didn't notice that. I meant OS4. I'll correct the original post in a moment.

Thanks for pointing that out.

Ah, OK. I'll try to swap them around tonight if I get a chance.
Thanks for the information.

That worked a treat - the difference is night and day.
Thank you, sir.

Haven't had a chance to test that yet but I'm sure you're right.
