Re: Vertical refresh and tearing...

[Lundberg, Johannes]

Hi

Yeah it is something I made myself and something I can not share. If I have some time I could write a short program that would demonstrate the tearing but I'm rather busy now so that is not so likely I think..  However, I think the person who wrote the backend should be able to answer the question easy..

Actually it is almost oyasumi (bed time)  :)

I am new to this group so I will not attempt to answer your question.  I have a question
for you:
 
Is the application something you downloaded from the GNUstep website?  If so,
could you say which application it is so that others could look at at in order to see
the effect you are observing?
 
If it is something you wrote, would you be able to share a short example demo
which would allow others to determine what is causing the problem?
 
ohayo or konichiwa as the case may be   (please excuse the spelling, if incorrect)

Subject: Vertical refresh and tearing...
To: discuss-gnustep@gnu.org

Hi

Currently it does not seem like rendering is synchronized with vertical refresh. Both my OpenGL (NSOpenGLView) app and a app using animated NSView has a lot of tearing (on FreeBSD with cairo backend).

Has anyone similar experiences or insight in what would be required to get rid of the tearing? Is it simply a matter of making additions to the code in the backend?

Best regards
