Modded Minecraft Stopped Working

I `pacman -Syu`'d and now Minecraft with Forge doesn't work. 

There are no log entries and no crash, it just hits 100% CPU on one core forever and `kill [PID]` doesn't make it go away, I have to `kill -9 [PID]`.

The hang occurs during launch around/right-after the texture related things like stitching textures and then "Texture creation - Uploading GL texture".

I replicate the issue with
* both Open and Oracle Javas
* a few compatible version combos of Forge and Minecraft (Minecraft Forge for 1.7.10 and 1.11.2 both fail)
* both ATLauncher and MultiMC
* several modpacks and Vanilla+Forge with no mods installed
* both Cinnamon and DWM

Vanilla Minecraft works fine.  I'd love to post on Forge forums instead of here, but it was working fine until I updated, so it seems much more like an OS issue.

I updated on the 20th and everything was fine, then I updated on the 25th and it broke.  This was a big update `[2017-05-25 06:57] [ALPM] upgraded linux (4.10.13-1 -> 4.11.2-1)` and many other things.  I'd suggest the kernel upgrade broke it, except that I think it broke right after the pacman without a reboot, so still old kernel (or would something about a kernel upgrade take immediate effect?).

How can I continue troubleshooting this issue with such a big upgrade but no file-system snapshots to revert?

Re: Modded Minecraft Stopped Working

This seems like the modded version's problem. Pacman is only responsible for updating official packages, it is your job to rebuild everything else against new libraries (same as the AUR, basically).

Re: Modded Minecraft Stopped Working

But this is Java; isn't it entirely portable?  It occurs to me that maybe downgrading java below u131 is worth a try, but what else sounds worth a shot?

Re: Modded Minecraft Stopped Working

How does the language it is written in make it special? Look at, or past if you don't know, your pacman log and see which of the modded versions dependencies were bumped.

Re: Modded Minecraft Stopped Working

Are you using mesa with radeonsi for graphics by any chance?

It seems mesa 17.1 introduced some regression causing some programs/games to trigger something alike an infinite loop in the driver, have seen both the forge splash screen and qupzilla getting frozen by this.

Haven't figured out what specifically causes this though... (Most programs run just fine after all)

You can disable the splash screen in `config/splash.properties` btw, which seems to fix the issue for the time being.

@GitOut, Genius.  Disabling splash made it work.  (Or the update I did today, but I doubt that.)

Does upstream have a bug report on it?

Re: Modded Minecraft Stopped Working

Have submitted a bug report describing this issue, could not work out what exact sequence of gl calls causes this, especially with it being slightly inconsistent.
