The two GLFW example programs which open a GLFW_FULLSCREEN window (pong3d and particles) fail to obtain that fullscreen window on my system but they don’t realize that they have failed, and so they merrily write into the video buffers incorrectly and obliterate the windowed X11 workstation screen terminally. (Need to restart X11 entirely after that, with loss of running apps.)
When GLFW_FULLSCREEN is replaced by GLFW_WINDOW, everything works as expected.
My SDL-based apps manage to switch the Linux desktop into fullscreen mode perfectly, and they end by reinstating the windowed X11 screen correctly on exit. This suggests that there is nothing inherently wrong with fullscreen operation on my Linux box here, as both GLFW and SDL are running through the same Mesa.
Is this a known bug?
