Full_Name: Keith Frost Version: 2.1.0 OS: Debian Sarge Submission from: (NULL) (66.162.141.10) This has actually been a problem for some time in R under Linux. (I noticed it under previous builds for Redhat 9 as well.) The graphics device windows produced by the x11() function do not always get redrawn when they should, sometimes leaving the device blank when there should be a graph on it. I do not know for sure that this is an R-specific problem (I suppose the window manager could be failing to pass along the correct redraw information), but I thought I'd try to find out if other people are experiencing it, and if it can be tracked down and fixed. To reproduce: Bring up a number of plots with the x11() function, and graph things on them. Move other windows to cover, and then reveal, the various plot windows, until -- one or more of your graphs disappears. Move the graphs over each other to get the graphs to come back. Etc.
X11 redraw events dropped? (PR#8250)

Please, your R is well out of date and you are asked NOT to submit bug reports on obselete versions. Nor, BTW, on things you are not sure are R bugs. The window manager hinting was changed in 2.2.0, and some people who used to experience this sort of thing say it is solved.
