Code Issues Projects Releases Packages Wiki Activity
fteqw/engine/gl/gl_vidlinuxglx.c
Shpoike 8dadfb4878 Added sys_openfile console command(and menu option) to web and flatpak(via cmake+dbus) builds, to 'install' packages on sandboxed systems a bit more easily. 
Cmake: Add FTE_WERROR option, defaults to true in debug builds and off in release builds (in case future compilers have issues).
Cmake: Pull in libXscreensaver so we don't get interrupted by screensavers when playing demos.
Make: Added `make webcl-rel` for a web build without server bloat (eg for sites focused on demo playback. Yes, this means you XantoM).
fteqcc: Include the decompiler in fteqcc (non-gui) builds ('-d' arg).
fteqcc: Decompiler can now mostly handle hexen2 mods without any unknown opcodes.
Allow ezHud and OpenSSL to be compiled as in-engine plugins, potentially for web and windows ports respectively.
Web: Fix support for ogg vorbis. Add support for voip.
Web: Added basic support for WebXR.
QTV: Don't try seeking on unseekable qtv streams. Don't spam when developer 1 is set.
QTV: add support for some eztv extensions.
MVD: added hack to use ktx's vweps in mvd where mvdsv doesn't bother to record the info.
qwfwd: hack around a hack in qwfwd, allowing it to work again.
recording: favour qwd in single player, instead of mvd.
Protocol: reduce client memory used for precache names. Bump maximum precache counts - some people are just abusive, yes you Orl.
hexen2: add enough clientside protocol compat to play the demo included with h2mp. lacks effects.
in_xflip: restored this setting.
fs_hidesyspaths: new cvar, defaults to enabled so you won't find your username or whatever turning up in screenshots or the like. change it to 0 before debuging stuff eg via 'path'.
gl_overbright_models: Added cvar to match QS.
netchan: Added MTU determination, we'll no longer fail to connect when routers stupidly drop icmp packets.
Win: try a few other versions of xinput too.
CSQC: Added a CSQC_GenerateMaterial function, to give the csqc a chance to generate custom materials.
MenuQC: Added support for the skeletal objects API.

/*
X11 is a huge pile of shit. I don't mean just the old x11 protocol, but all the _current_ standards that don't even try to fix the issues too.
Its fucking retarded the crap that you have to do to get something to work.
timeouts to ensure alt+tab between two apps doesn't fuck up gamma ramps is NOT a nice thing to have to do.
_MOUSE_ grabs cause alt+tab to fuck up
if I use xinput2 to get raw mouse events (so that I don't have to use some random hack to disable acceleration and risk failing to reset it on crashes), then the mouse still moves outside of our window, and trying to fire then looses focus...
xf86vm extension results in scrolling around a larger viewport. dependant upon the mouse position. even if we constrain the mouse to our window, it'll still scroll.
warping the pointer still triggers 'raw' mouse move events. in what world does that make any sense?!?
alt-tab task lists are a window in their own right. that's okay, but what's not okay is that they destroy that window without giving focus to the new window first, so the old one gets focus and that fucks everything up too. yay for timeouts.
to allow alt-tabbing with window managers that do not respect requests to not shove stuff on us, we have to hide ourselves completely and create a separate window that can still accept focus from the window manager. its fecking vile.
window managers reparent us too, in much the same way. which is a bad thing because we keep getting reparented and that makes a mess of focus events. its a nightmare.
the whole thing is bloody retarded.
none of these issues will be fixed by a compositing window manager, because there's still a window manager there.

(specifically, the panning width+height values are recalculated (completely ignoring any passed args), but left+top are not, the tracking+border areas are preserved but affect nothing)
the workaround is to:
lock the server (so other programs don't bug out too much),
disable the screen (for the next step to work),
change the virtual size to one that won't cause a problem with panning,
re-enable the screen with the desired video mode,
and unlock the server again.
This will not help with multimonitor setups, xrandr video mode switches are disabled entirely there.
