[STR New] Link: http://www.fltk.org/str.php?L2152 Version: 1.3-current No, I don't think so (i.e. no duplicate). I checked this already, but IMHO it's more the opposite. This STR is about enlarging a window with XDBE enabled, and STR #2039 seems to be a problem with shrinking a window, but with only some (or maybe one) window manager(s). However, I could also be wrong. To this STR (#2152): I'm not familiar with X11/XDBE internals, but my impression was that FLTK is doing something like its own double buffering - maybe only if "real" double buffering is not available. Is this possible, maybe with an Fl_Offscreen? Then, when the window is enlarged, the increased window size is "lost" somehow, and the new (bigger) part of the window is never drawn. At least that's how it looks. The widgets seem to resize, but there's a black or otherwise undrawn part of the window. New tests: It looks like an interaction with X servers and/or window managers. I just started the app (test/tabs) on an Ubuntu Linux system (a VM = virtual machine) and redirected the output to different X servers: (1) local: works (2) VM with Fedora 11: works (3) Windows 7 with Cygwin X server: fails (4) Windows XP with older Cygwin X server: fails with warning The warning written to stderr is: 'Xlib: extension "Generic Event Extension" missing on display "localhost:12.0".' The server localhost:12.0 is the correct server (ssh X forwarding), and the app runs, but shows the fault. Does anybody know what X server part (module/lib) might contain this? I tried with libxcb (runtime), but this didn't change the symptoms. If this is a Cygwin X server problem, then we could probably close this STR. Continuing tests...
