After upgrading mesa-21.1.6-1 to mesa-21.2.1-1 Google Chrome, Chromium and all browsers based on Chromium can't activate Vulkan support.
I use 92.0.4515.159 (Official Build) (64-bit). #enable-vulkan flag is enabled.
If I start browser with chrome://gpu page opened by default I see how it starts with 'Vulkan: enabled', but then flickers a couple of times and Vulkan switches off automatically and the page shows 'Vulkan: disable'. Scrolling becomes noticeably slower and choppy.
In order to restore Vulkan support I need just to downgrade mesa to 21.1.6-1 and it starts working

Additional info:
* package version(s)
* config and/or log files etc.
* link to upstream bug report, if any


mesa updates together with libva-mesa-driver, vulkan-intel and vulkan-mesa-layers. But in order to reproduce the issue I can leave those at 21.1.6-1 and just update mesa, the issue can be reproduced this way as well.

I use integrated GPU in Intel(R) Core(TM) i7-8650U:

Extended renderer info (GLX_MESA_query_renderer):
Vendor: Intel (0x8086)
Device: Mesa Intel(R) UHD Graphics 620 (KBL GT2) (0x5917)
Version: 21.1.6

$ cat ~/.config/chrome-flags.conf

Steps to reproduce:

1. Use packages mesa, libva-mesa-driver, vulkan-intel and vulkan-mesa-layers version 21.1.6-1. Chrome, Chromium, version 92.
2. Enable Vulkan support in Chrome or Chromium browser using #enable-vulkan flag. Verify Vulkan is enabled on chrome://gpu page.
3. Update mesa-21.1.6-1 to mesa-21.2.1-1. Alone or with libva-mesa-driver, vulkan-intel and vulkan-mesa-layers.
4. Start the browser. You will see 'Vulkan: disabled' despite enabled #enable-vulkan flag. Window may flicker a couple of times.
This task depends upon

Did you file an upstream bug report ? (
