I was curious if there is a way to eliminate flicker in various places in Fvwm, specifically FvwmButtons and icons. Flicker occurs in a few places, for instance:
My clock is powered by a FvwmScript that is updated every minute, that is swallowed inside a FvwmButton. Everytime it updates you can see a very quick flicker.
I have an image that sits inside a FvwmButton. I have it set so if I click on an area on my desktop this image will slide into view. The image slides in very clean, but when it stops there is a quick flicker, where I see the wallpaper underneath, then it looks fine.
I use Taviso’s thumbnail function for my icons. I also have a transparency set for each, so when I mouse-over the image it returns to being 100% opaque. When I mouse over another icon, when it returns from opaque to tansparent there is a flicker.
I’m assuming that all 3 of these problems are related to Fvwm’s repaint method. Is there an option to enable double buffering? Is this something that could be eliminated with a patch?
I am using the FlickeringMoveWorkaround, but I believe this is for a different issue anyways.
