issue with ofTexture, wierd lines inside rectangles #98

Closed kalwalt closed 11 years ago

kalwalt commented 11 years ago

hte issue is concerning the textureExample. some coloured lines appear in the transparent one and coloured one rectangles. see the picture . I haven't any errrors from the compiler or in a console while launching the app. Normally this not happens whit my notebook in Ubuntu 64 bit or 32bit. And it'is not temporary but always happens. what could be? Is it easy to fix? Istantanea - 03012013 - 14:08:11

forgot to mention: i'm using a PandaboardES.

arturoc commented 11 years ago

don't see anything wrong with it, can you post an image of what you see in 32/64bit linux? i'm seeing the same on the pandaboard and my computer and it looks like the screenshot you posted except the colors in the 2nd gradient look different but it could be something with the screen capture?

kalwalt commented 11 years ago

yeah, in the screenshot it'is difficult to see due to the screen size and resolution. But i can see using my pandaboard. Strange that you don't encounter with your pandaboard. but maybe it'is a problem of the desktop manager? i'm using xubuntu on my Pandaboard. Above there is a picture from my notebook. I will do another shot from my Pandaboard probably tomorrow, now i'm bit busy. Schermata del 2013-01-03 16:04:15

These images look fine to me -- perhaps you could snap photo with a camera or something to demo the onscreen issue?

kalwalt commented 11 years ago

I have taken a shot with my nikon coolpix. Now you should see these thiny blue lines (thick line of one pixel). Looks where are red arrows. textureExample

arturoc commented 11 years ago

what resolution do you have the screen? it could be a scaling issue because of not using the native resolution of your screen

bakercp commented 11 years ago

Any movement on this issue @kalwalt ?

kalwalt commented 11 years ago

this issue is not related to OF. It happens also with other app. I tried to scaling the resolution of the screen with xrandr and with arandr but the issue persist with other res. I think is related to depth bit resolution probably is used a 16 bit instead of a 24 bit , but when i changed the boot.scr like this:

fatload mmc 0:1 0x80000000 uImage fatload mmc 0:1 0x81600000 uInitrd

setenv bootargs ro elevator=noop console=ttyO2,115200n8 mem=1G@0x80000000 omapfb.mode=dvi:1920x1080MR-24@60 omapdss.def_disp=dvi root=UUID=9fa19eaf-39a4-4e71-992f-de8d037a43e3 fixrtc splash

   bootm 0x80000000 0x81600000

i have no output on dvi . I think i will ask support on Pandaboard google group that is the best place for ask it. Thanks

bakercp commented 11 years ago

Very odd. perhaps pandaboard forums will be better. I'm closing this for now.
