I have the following problem: when a window is obscured and then made visible again the obscured part is lost. I have tried grx245 and grx246 on Debian Woody with KDE. The problem vanishes when the display is redirected to a machine which uses fvwm as a window manager.
I long I can see the only effort grx makes to make display persistent is to request backing store. My impression was that backing store is always optional. For my own simple program I used pixmap as a window background and directed all drawing to that pixmap -- it works on the machine where grx method failed. So the question is if grx method to avoid refresh should be changed?
