Cacko 1.23: Strange Rendering Problem

[guima]

Hi,

I have just installed the cacko ROM version 1.23 lite on my SL-C860.
The full version number is ROM 1.23 1539311005.
The linux kernel is: 2.4.18-rmk7-pxa3-emb

The ROM works great almost everything works out of the box without trouble.
However, the screen rendering has a problem.

It seems like every 3rd or 4th horizontal line is displaced vertically by 20 lines down.
The effect looks has if there is a soft shadow just below the main image.
First I noticed this in the splash screen and it looks like as if there is some fancy shadowing effect of the fonts (which even looks cool). Unfortunately this is happening during real operation of the PDA (not only on the "cool" splash screen).
The effect happens mostly on the top and bottom of the screen.

I am suprised about it since I would imagine that if this was a common problem it would have been reported and fixed long ago.
However, I was just running the pdaxrom and I didn't have any such problem so I don't think it is my own hardware either. The same holds for the original Sharp ROM which I used long ago.

Any ideas?

Thanks
Joao

I have also tried the standard (non-lite) ROM with the same effects.
Now, I am using the OZ rom and the effect is gone. The screen is working normally.
So, it is clearly a problem with Cacko....

Let me know if anyone knows a fix for this, I really like the stability of the ROM otherwise.

Thanks.
Joao

search for lcd com and phase adjust in the dm menu, thats probably where your problem lies

Thanks bam. That worked.
I had to do some searching because I didn't know what was the "dm menu".
There are lots of details about this issue in the following thread for the pdaxrom.

I am guessing that if now I want to go back to the pdaxrom I will have to tune this again!
For the record, my settings are now: lcd com: 119 (changed from 114); phase adjust: 0 (changed from +5).
