Last night before updating, I was able to run 32-bit applications that used vulkan. (Namely WINE-based things. 32-bit applications that do not use vulkan are fine, nearly as I can tell. I don't have any 32-bit applications that don't use WINE.)

Note, I did not update gcc and related packages and the kernel (headers, source, modules, and firmware) because gcc for multilib hasn't upgraded yet.

After the upgrade, any 32-bit application that uses vulkan either hangs or crashes. 64-bit vulkan applications are fine.

I'm getting this error in WINE with any 32-bit program using dxvk: /usr/bin/vkcube works
/usr/bin/32/vkcube segfaults (Just "zsh: segmentation fault /usr/bin/32/vkcube")

Things I've tried:

1.) upgrading WINE to wine-staging 5.4
2.) uninstalling and reinstalling my video card drivers (Nvidia 440.64)
3.) Aside from gcc and the kernel, checking for anything I've missed with install-new and install multilib.

Any ideas what might be going wrong and what I did wrong? Or is this an issue with the fact that I haven't upgraded gcc yet? Or is this a sign I should finally play Witcher 3 (64-bit?)

I'm using vulkan-sdk-1.2.131.1 for both 64-bit and 32-bit.

Thinking about it...vulkan-sdk-1.2.131 was compiled for wayland support. Does multilib need to add wayland?

x/wayland-1.18.0-x86_64-1.txz
x/wayland-protocols-1.18-noarch-1.txz

Would these be the only two needed for multilib, if the lack of wayland is a problem for vulkan-sdk?

Some games that used Steam Play stopped working after the Friday update.

Out of curiosity, which ones? 64-bit or 32-bit?

Jet Set Radio, Hellsinker, King of Fighters XIII, Samurai Shodown V Special, Sonic Mania, Valkyria Chronicles, Spore, Tomb Raider: Anniversary, and Ikaruga no longer load. Cloudbuilt, DeadCore, Wuppo, Doom 2016, Yakuza 0, Tekken 7, The Witcher, F-19 Stealth Fighter, and SoulCaliburVI work. The ones that don't work are probably all 32 bit. I suppose Cloudbuilt, Deadcore, and the Witcher are 32 bit.

Steamplay has d9vk (dxvk) on by default. Try launching with PROTON_USE_D9VK=0 %command%? Sims 3 doesn't work (needs d9vk and vulkan), but Geneforge 1 does (opengl)

ETA: could be PROTON_USE_DXVK, too. I think it changed with 1.5.5.

I tried it on a few games and they still do not work.

Here's everything that changed on Friday March 13:

SDL2 is used for wine/proton. I focused on vulkan, because it seemed like vulkan things that were breaking, and /usr/bin/32/vkcube segfaults. vulkan-sdk was compiled against wayland, and so was SDL2.

So does multilib need wayland and wayland-protocols? Will I harm anything if I install them for multilib? (using convertpkg-compat32, of course.)

Isn't Wayland still only an option? Isn't Steam, and perhaps Vulkan, just accommodating that option? I ask this because it is my understanding nVidia graphics doesn't yet support Wayland and I can't begin to imagine Steam or anyone else essentially locking out that huge segment of their Users.

I don't yet game on -Current so I may be way off the mark but I wonder if the "zero devices found" error is due to such current incompatibility.

I"m not using wayland, but vulkan-sdk is compiled against wayland, which isn't there on the 32-bit end of things. 64-bit vulkan works fine (heh), and wayland is installed.

Another data point with vulkan-sdk (and possibly missing wayland) is that I installed Guild Wars into a clean wineprefix with no dxvk, and it started right up.

Vulkan-sdk-compat32 was upgraded March 6, but SDL2 was upgraded last Friday. Both were rebuilt against wayland, and SDL2 does provide a back end for wayland.

I was using Proton 5.0-4 and does not work. However, I forced Proton 4.11-13 and the games I tested started working.

Hey, try PROTON_USE_WINED3D=1 (from: https://github.com/ValveSoftware/Pro...g/proton-5.0-1)

Yes, that command worked!

OK...so the issue is with vulkan. From the changelog:

l/SDL2-2.0.10-x86_64-2.txz: Rebuilt.
Rebuilt to pick up wayland support. Thanks to franzen.

SLD2-compat32 was upgraded Friday night.

Will adding wayland and wayland-protocols to mulitlib hurt anything?

OK, I have a fix.

Download x/wayland for 32-bit.
convertpkg-compat32 -i wayland-1.8.0-i586-1.txz (whatever it's up to version-wise)
upgradepkg --install-new /tmp/wayland-1.8.whatever-it-was-named-compat32.txz

Guild wars, at least, worked for me.
