Bug (OS X, Nex 2.5); move non-fullscreen Nex = cursor broken

Postby exitcode1 » Tue Apr 07, 2009 2:25 pm

Just reporting a problem I've hit... I wanted to play in a window on my bigger attached monitor rather than my laptop's built-in screen and found that when I switched out of full screen and moved the Nex window over to my external monitor, the cursor broke.

Steps to reproduce: unzip 2.5, open game, open settings, open video, turn off "Full Screen", switch to another program (command-tab), move Nexuiz window, try to play. Curiously, you can move it a few pixels and it will still work. If you move 100 or so however, even if the main menu sections are still mostly lined up pixel-wise with where they were, nothing works. Nothing odd in the log.

I wanted to eliminate my very mucked-around-with machine as the cause so in addition to that machine (a fully up-to-date MacBook Pro), I tested with a newly unboxed MacBook using the just the internal trackpad and the internal LCD, and an iMac with a Kensington mouse and their MouseWorks drivers. Untested on other OSes.

How is that multi monitoring done on mac? On linux/x11 i once had similar problems when using xinerama.. however basicly ALL 3d apps had that problem then. I only had that problem though when i had the screens in a certain order (left/right). I think i posted that on the nvidia forums but never got a response.. and now i mostly use my laptop OR attach a 24" to it and set the gfx to display the same image on both and just close the laptop :)

mirroring vs 'extended desktop'

Postby exitcode1 » Tue Apr 07, 2009 4:07 pm

Yeah, for years now, all Macs have had dvi/mini-dvi/displayport output for external video and if the graphics card could handle it (they all can these days), you could turn off the mirroring of the built-in screen to the external screen. Same as 'extended desktop' mode in windows, etc you can arrange them digitally to match the irl setup.

In any case, I suspected a per-screen opengl context mess to be the culprit until I tried moving the window around on a machine with no external monitor and had the same problem.

I'm not sure.. i do not even own a mac.. If you are or know a mac developer that can/wants to help there, that would be surely welcome!
