Does this happen in Linux as well?
I was able to make Gnome 3's notifications say on screen while the game is running. It's also possible to make the Gnome 3's notifications area visible by just moving the mouse to bottom-right corner.
No, doesn't happen on Linux, since D3D isn't a renderer option there. Doesn't happen on either OpenGL or software renderers both in Linux and Windows.
I was encouraged to post this here, when I noticed aiusepsi reported crashing issues during resolution changes on Windows.
@zer0def, using the technique @Sinihopea mentioned, can you reproduce?
I know D3D isn't a render option on Linux (and even if it was, it'd be non-functional), but there are strange things that often happen with the porting. For example, many people (myself included) have noticed some improvements in TF2's performance when using dxlevel flags, despite DX not being usable on Linux.
Just trying to gain as much information about the situation as possible.
Couldn't reproduce Sinihopea's scenario on Mint Debian Edition XFCE UP6, Lubuntu 12.10 and Arch /w LXDE.
Attempts to install and run Gnome3 on the same Arch install resulted in not being able to boot into it anymore, though. :)
Reporting Windows (and OSX) bugs for Half-Life and CS 1.6 is welcomed here, I am using this github to collect them all.
I'm removing d3d support, you actually have opengl rendering above, but not quite correctly due to the d3d flag. I've improved the OGL rendering path and added new features, doing this in the ancient d3d interface we use is not reasonable and given widespread ogl support (and the low demands of hl1) d3d is no longer useful.
There are still some leftovers from D3D, if that matters:
gl_d3dflip
vid_d3d
EDIT:
Maybe it would be a good idea to remove software mode as well?
There were some exploits with it that allowed you to disable smokes and flash grenades, not sure if it's still possible.
Nothing extracted yet.
When running HL1 in fullscreen using the D3D renderer, Windows taskbar appears on top of the screen.
