Description:
With up-to-date Arch Linux and testing repos enabled, surfing some websites on Firefox causes Xorg to crash. An example website is https://store.kde.org/p/1327319. If I downgraded mesa to 20.1.0-1, everything seems fine. Additional info: Crash log from ~/.local/share/xorg/Xorg.0.log [132368.267] (EE) Backtrace: [132368.267] (EE) 0: /usr/lib/Xorg (xorg_backtrace+0x4d) [0x558a0ef7976d] [132368.267] (EE) 1: /usr/lib/Xorg (0x558a0eec6000+0xa9cd8) [0x558a0ef6fcd8] [132368.267] (EE) 2: /usr/lib/libc.so.6 (0x7fc25518d000+0x3c3e0) [0x7fc2551c93e0] [132368.267] (EE) 3: /usr/lib/dri/i965_dri.so (0x7fc253229000+0x149247) [0x7fc253372247] [132368.267] (EE) 4: /usr/lib/libgbm.so.1 (0x7fc25535b000+0x5991) [0x7fc255360991] [132368.267] (EE) 5: /usr/lib/xorg/modules/libglamoregl.so (glamor_egl_fds_from_pixmap+0x5b) [0x7fc25420f61b] [132368.267] (EE) 6: /usr/lib/Xorg (0x558a0eec6000+0x9efd7) [0x558a0ef64fd7] [132368.267] (EE) 7: /usr/lib/Xorg (0x558a0eec6000+0x39068) [0x558a0eeff068] [132368.267] (EE) 8: /usr/lib/libc.so.6 (__libc_start_main+0xf2) [0x7fc2551b4002] [132368.267] (EE) 9: /usr/lib/Xorg (_start+0x2e) [0x558a0eeff39e] [132368.267] (EE) [132368.267] (EE) Segmentation fault at address 0x130 Full Xorg.0.log is attached below. Environment: Intel HD Graphics 4600 on i7-4770. I also have an ancient GeForce GTS 450 but I don't think it's enabled. Steps to reproduce: Put `firefox https://store.kde.org/p/1327319` to ~/.xinitrc and run startx. I use SDDM+LXQt+kwin, so I use xinit to make sure the bug is not from qt 5.15. |

Edit: Commented upstream with a sparse backtrace: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/4861#note_516720
Crash: Intel(R) Core(TM) i5-4570 CPU @ 3.20GHz
Intel(R) Pentium(R) CPU B960 @ 2.20GHz
Fine: Intel(R) Core(TM) i5-7400 CPU @ 3.00GHz
Seems that this affects only old Intel processors (I don't have any AMD system at hand).
