| xtalmath | Hi, I am programming a graphics application in opengl, I recently upgraded to 12.04. Now all pure black pixels become transparent for _some_ kinds of graphics applications, for now I only see flash videos. | 06:26 |
| xtalmath | I am running the proprietary nvidia driver. | 06:26 |
| xtalmath | does the nvidia driver treat flash applications specially different from other applications? | 06:27 |
| xtalmath | the operating system / driver should not permit flash to draw in other applications windows | 06:28 |
| xtalmath | I would like to isolate the specific function calls that render to "whatever the name is" of the buffer that is drawn before/underneath applications whose black pixels are treated as transparent | 06:30 |
| xtalmath | btw a while back I came here for vsync issues which I finally resolved, in case anyone care how I did so | 06:34 |
| xtalmath | I am not entirely sure which of the following 2 steps solved it: installed gnome-session-fallback (everything was much lighter/faster,...), then sudo /usr/lib/lightdm/lightdm-set-defaults -s gnome-fallback | 06:36 |
| xtalmath | which was step 1 then I did sudo nvidia-xconfig --no-composite, after wich tearing was gone... | 06:37 |
| xtalmath | but both before and after these operations black was transparent for at least flash video's | 06:37 |
| xtalmath | also, as I said I was programming in opengl, I did a quick test: drew a black background with a colored primitive on top. without flash it worked as expected. with flash video running the youtube video was visible where my application should display black. | 06:39 |
| xtalmath | then I ran 2 instances (call them gl1 and gl2) of my application at the same time to see if gl1's primitive was visible in gl2's black area or vice versa, but only the youtube video showed through... | 06:40 |
| xtalmath | => there is a specific buffer (I guess in Nvidia's driver or card) which can get rendered too, and all pure black on the final image of the traditional graphics stack is replaced with pixels from this specific buffer... | 06:42 |
| xtalmath | so disabling flash to render to it or similar does not seem the right solution, the OS/driver combo should simply not allow one application to draw in anothers area... | 06:42 |
