Hi I don't know if anybody has reported this before, I did not find any thread covering this (on BvisionPPC.. I know there are threads regarding video problems with mediators/voodoo).
I'm running OS4 classic on my Amiga 1200 with BlizzardPPC and BVision. My problem is that everytime I use a screenmode higher than 1600x1200 (16 bit), some horizontal and white lines appear randomly on the screen, like little sparks... they appear too when I move a window, around window edges... I guess this is a software driver problem, 'cause higher screen modes like 1792x1344 work just perfect on OS 3.x. I even had a lockup while browsing WB menus while my WB was set in this screenmode and the mentioned lines were appearing in OS4.
The problem shows too but more slightly in 1280x1024x24 (yes, only in 24 bit). I'm using the new method to create screenmodes (tooltypes in the monitor file), I have't created any screenmode usinig p96mode. Here's how my monitor's tooltypes look:
VSYNCMIN=50
VSYNCMAX=160
HSYNCMIN=31500
HSYNCMAX=95000
MODE=640x400@85
MODE=640x480@85
MODE=800x600@56
MODE=1024x768@56
MODE=1280x960@56
MODE=1280x1024@56
MODE=1600x1200@56
MODE=1792x1344@60
MODE=1856x1392@60
MODE=1920x1440@56
(FAKENATIVEMODES=Yes)
INTERRUPT=No
So, the problem shows up on:
1792x1344x16
1856x1392x16
1920x1440x16
and 1280x1024x24 (it shows as 1280x1024x32 in the screenmode list). There is something weird with THIS mode, it shows up in the screenmode list at first boot, but after a softreset, it doesn't!!).
The problem is more visible while the WB is on any of these screenmodes and you drag a window around, you will see the lines around the edges. And it's even more visible if you have black blackground.
Anyway, I'm pretty sure this is a problem in p96 video drivers in OS4, because I have similar screenmodes under CGFX in OS3.9 without any problem at all.
Comments/suggestions?
Thanks!
D.
