Force rendering on gemhead not working #413

It works here under MacOS Sonoma, same Gem version and pd-0.54-1

i'm also unsure whether i understand the problem.

in double-buffer mode (the default):

  1. the drawing actually happens to an off-screen buffer, that is only swapped onto the window when the [gemwin] triggers
    • so whatever you are drawing is not immediately visible
  2. the [gemwin] triggers a clear buffer first
    • so whatever you have drawn into the off-screen buffer with force-rendering is cleared

the help-patch doesn't really show (nor explain) this. it also renders the all three geos anyhow (except for the [square], which can be turned off), so forcing a rendering of the [circle] wouldn't really look different. however, if you watch the PdConsole, you should see that when banging the [gemhead], you do get a FORCEABLE: gemList printout - at least if there's a an active GemWindow.

Sorry for the confusion, now i understand better the way it is working. I tried the things you mentioned, the are working fine. So there is not an issue anymore.
