Mesa applications becomes almost unresponsive after a few seconds of running. For example glxgears is expected to rotate the contents of the window when pressing arrow keys and exiting when pressing escape. However the application seems almost unresponsive to key presses (Holding down keys for a couple of seconds or pressing keys repeatedly can make the application respond to them occasionally). The affected applications are also reacting with a delay of a few seconds when closing the containing window (that is the window is not immediately closed when pressing the close window button of a window manager). This bug is present using several different window managers and even when launching the apps from xterm in a bare x-server launched with xinit. This bug is present at my computer with the nv driver but not with the nvidia proprietary driver. Note that mesa apps were working as expected before i upgraded from XFree4 to xorg.
I want to add that the mesa applications still seem to render reasonably well, for example glxgears renders with 100-200 fps with the nv driver.
Whats the status of this bug using a current version of xorg?
I think this is largely due to indirect rendering and if anything a bug in the apps, not the server. Apps should use glFinish() to ensure interactivity.
