Other programs shadows conflicts with oF

Hi,

I have a problem with oF on my computer: when other sub windows that has shadows are on top of the oF window, the shadow is “blinking” and very annoying on the oF screen around the sub window. it seems like a sync problem, and it’s blinking less when oF framerate is set low. is this a problem on windows only? I use XP and MVS2005. I get this problem with sub windows in max/msp 5.0.3

What kind of graphics card do you have? I’ve run into weird blinking-ish issues with my nvidia card…

If you suspect it’s a vertical sync issue, you can try turning on vertical sync: http://www.openframeworks.cc/documentation#ofUtils-ofSetVerticalSync

Hey, that solved the problem, thanks! I thought I had already tried that… What’s wrong with my system if there is trouble with vertical sync? I have a Radeon X1650 card.

I don’t think it’s a problem with your system, but just how windows get redrawn by the OS. I don’t know how windowing on Windows works though – maybe someone else does?

This problem can be more or less fixed by turning off shadows under menus in windows visual effects settings:

control panel -> system (properties) -> advanced -> performance settings -> visual effects

Here uncheck “Show shadows under menus”.

This wont fix a similar problem with tips type popups (like when mouse is over a menu item) that gets on top of the oF window.
