al_set_new_display_flags question

Is it possible to set multiple display flag options in Allegro 5? I have three displays and am using the ALLEGRO_FRAMELESS option but would like to try the ALLEGRO_OPENGL option with it. I tried adding the opengl option but got two displays with a frame.

Thanks. Not the result I was hoping for though.

Could you post some reduced code?

I could try to reproduce it at least.

The problem I was trying to resolve was a timer issue. A print statement seemed to be drawing at erratic intervals. First I read d3d is not as reliable as opengl so I thought I would try it. That did not work, So I then put a counter in my code to trigger the redraw at specified intervals and it seems to work. But if you want to play with it, you can divide your screen into three untitled displays, add the al_set_new_display_flags option with the opengl flag, then another statement setting the display_flags to the untitled option.

<edit> The project is full screen, top to bottom, and the middle display was much smaller in height than the two others.
