            Bug ID: 259773
           Summary: REGRESSION(264514 at main): [WPE] Lot of crashes when
                    running layout tests on machines without a GPU
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WPE WebKit

264514 at main updated several recipes on the Flatpak SDK.

Among them it updated the FDO junction from freedesktop-sdk-22.08.11-24-g67b3605b402cffed2db0344f1da3a6acb5b6c914 to freedesktop-sdk-22.08.11-127-g7bed8a0d05bfd13939862b30e7080d1ffd5f635b

And that it turn updated Mesa from mesa-23.0.3-0-g77661a60228061aa5d78107e0de5c58c803a57a4 to mesa-23.1.0-0-gbe4f7fb656180ab55a50eff01f36672b0bf5f146


And there is a regression with the new version of Mesa that is causing massive crashes on the WPE bots that run without a GPU (which happen to be all the EWS machines).

You can see how they are crashing with more than 500 crashes (exit early) since then: https://ews-build.webkit.org/#/builders/34


I have been able to reproduce the issue by building Mesa with jhbuild (for faster iteration) and I'm now bisecting Mesa to find out which Mesa commit caused this
