Issue 580 in xmonad: WIndows using OpenGL don't resize properly when partially offscreen

Status: New Owner: ---- New issue 580 by StevensE...@gmail.com: WIndows using OpenGL don't resize properly when partially offscreen https://code.google.com/p/xmonad/issues/detail?id=580 What steps will reproduce the problem? 1. Start a program that uses OpenGL such as glxgears 2. Drag the program window partially off the top of the screen 3. Resize the window to be longer vertically What is the expected output? What do you see instead? I expect to see the window expand to fill the new space. Instead I see a blank black space in that area (for glxgears, for my own personal program at https://gitorious.org/linted/linted I see old and stale data from what was last drawn there by other programs.) What version of the product are you using? On what operating system? $ xmonad --version xmonad 0.11 $ uname -a Linux proteus 3.17.2-gnu #1 SMP Thu Oct 30 19:27:36 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux I'm using Trisquel 7 from trisquel.info and the Linux-Libre kernel from http://www.fsfla.org/ikiwiki/selibre/linux-libre/ Are you using an xmonad.hs? Please attach it and the output of "xmonad --recompile". xmonad --recompile gives no errors or warnings. My xmonad.hs is attached. Please provide any additional information below. Two pictures of the bug are provided.

Comment #2 on issue 580 by allber...@gmail.com: WIndows using OpenGL don't resize properly when partially offscreen https://code.google.com/p/xmonad/issues/detail?id=580 Window contents, including redrawing, is not under the control of the window manager. When the window is resized, the X server sends Expose events... but I admit I do not know how this is reflected to OpenGL programs, which do not talk to the X server directly. In any case, it is more or less xorg driver <-> X server (Mesa component in the case of OpenGL) <-> program, with the window manager only involved in the interaction with the user during the resize. -- You received this message because this project is configured to send all issue notifications to this address.
