Antialiasing disabled

[ericwa]

Seems like antialiasing got disabled at some point in the last month or so..

Screenshot I took last week on d190c59 / macOS:

muk0r reports it on the f7fe54e Windows build from appveyor:

I'm not sure when AA was last working

[muk0r]

The "previous build" I mention is "2db2dad", by the way. Sorry for the lack of clarity

[kduske]

Fixed in 7ce181f.

Still present in RC3 -

Fedora 25, any other specs I need to provide?

[ericwa]

I can reproduce, with the RC3 .rpm installed on a Fedora 25 VM in VirtualBox, with software OpenGL... but that may just not support multisampling.

What's in the console after launching TB and creating a new map?
I get:
"Renderer info: Gallium 0.4 on llvmpipe ...
Depth buffer bits: 32
Multisampling disabled"

[ericwa]

Yeah, sounds like the llvmpipe software renderer just doesn't have multisampling: https://lists.freedesktop.org/archives/mesa-dev/2015-June/086674.html
So in my case TB is behaving as expected.

Here's what I've got in my console, for posterity.

No, TB's console.

[kduske]

On my Xubuntu Parallels VM, I get reported that multisampling is enabled, but it the display looks jagged. I have to admit that I don't really care about this. If wxWidgets reports that it works, but then it doesn't, it's either a driver problem or a wxWidgets problem.

[kduske]

Console reports

Renderer info: Parallels using AMD Radeon R9 M395X OpenGL Engine version 2.1 ATI-1.48.16 from Parallels and ATI Technologies Inc.
Depth buffer bits: 24
Multisampling enabled
Creating new document
Loaded entity definition file Quake.fgd

[kduske]

Addendum: I think that it worked in Parallels VMs at some point. Also, I made sure that our glx11 patch was applied to wxWidgets in my VM. I'm going to try the official TB2 RC3 deb also.

[kduske]

Same with the deb package on a fresh install.

[ericwa]

Just tried the RC3 deb on real hardware with Ubuntu 16.04, nvidia 9400m, open source (nouveau) drivers.. it works here; prints "Multisampling enabled" in the TB console and it's indeed multisampled.

[kduske]

Alright then. I don't think it's a problem with TB.
