I have a Chrome 55 app-mode window that is over time able to get itself into a weird state, where it doesn't update the contents properly anymore, then closing and relaunching it crashes Xwayland. This is on kernel 4.9.0, gnome-3.22, Gentoo. dets 19 21:25:05 papaya org.gnome.Shell.desktop[18687]: (EE) dets 19 21:25:05 papaya org.gnome.Shell.desktop[18687]: (EE) Backtrace: dets 19 21:25:05 papaya org.gnome.Shell.desktop[18687]: (EE) 0: /usr/bin/Xwayland (xorg_backtrace+0x56) [0x57cf36] dets 19 21:25:05 papaya org.gnome.Shell.desktop[18687]: (EE) 1: /usr/bin/Xwayland (0x400000+0x1808c9) [0x5808c9] dets 19 21:25:05 papaya org.gnome.Shell.desktop[18687]: (EE) 2: /lib64/libpthread.so.0 (0x7fbf59455000+0x10d70) [0x7fbf59465d70] dets 19 21:25:05 papaya org.gnome.Shell.desktop[18687]: (EE) 3: /usr/bin/Xwayland (WriteFdToClient+0x4) [0x57fbb4] dets 19 21:25:05 papaya org.gnome.Shell.desktop[18687]: (EE) 4: /usr/bin/Xwayland (dri3_send_open_reply+0x6d) [0x4e785d] dets 19 21:25:05 papaya org.gnome.Shell.desktop[18687]: (EE) 5: /usr/bin/Xwayland (0x400000+0x29747) [0x429747] dets 19 21:25:05 papaya org.gnome.Shell.desktop[18687]: (EE) 6: /usr/lib64/libffi.so.6 (ffi_call_unix64+0x4c) [0x7fbf58ca0020] dets 19 21:25:05 papaya org.gnome.Shell.desktop[18687]: (EE) 7: /usr/lib64/libffi.so.6 (ffi_call+0x2f8) [0x7fbf58c9fa88] dets 19 21:25:05 papaya org.gnome.Shell.desktop[18687]: (EE) 8: /usr/lib64/libwayland-client.so.0 (0x7fbf5ade1000+0x8f3a) [0x7fbf5ade9f3a] dets 19 21:25:05 papaya org.gnome.Shell.desktop[18687]: (EE) 9: /usr/lib64/libwayland-client.so.0 (0x7fbf5ade1000+0x5cf0) [0x7fbf5ade6cf0] dets 19 21:25:05 papaya org.gnome.Shell.desktop[18687]: (EE) 10: /usr/lib64/libwayland-client.so.0 (wl_display_dispatch_queue_pending+0x7c) [0x7fbf5ade7f3c] dets 19 21:25:05 papaya org.gnome.Shell.desktop[18687]: (EE) 11: /usr/bin/Xwayland (0x400000+0x2390b) [0x42390b] dets 19 21:25:05 papaya org.gnome.Shell.desktop[18687]: (EE) 12: /usr/bin/Xwayland (0x400000+0x181312) [0x581312] dets 19 21:25:05 papaya org.gnome.Shell.desktop[18687]: (EE) 13: /usr/bin/Xwayland (WaitForSomething+0x1eb) [0x57b1ab] dets 19 21:25:05 papaya org.gnome.Shell.desktop[18687]: (EE) 14: /usr/bin/Xwayland (0x400000+0x148e71) [0x548e71] dets 19 21:25:05 papaya org.gnome.Shell.desktop[18687]: (EE) 15: /usr/bin/Xwayland (0x400000+0x14d198) [0x54d198] dets 19 21:25:05 papaya org.gnome.Shell.desktop[18687]: (EE) 16: /lib64/libc.so.6 (__libc_start_main+0xf0) [0x7fbf590d9620] dets 19 21:25:05 papaya org.gnome.Shell.desktop[18687]: (EE) 17: /usr/bin/Xwayland (_start+0x29) [0x422ff9] dets 19 21:25:05 papaya org.gnome.Shell.desktop[18687]: (EE) dets 19 21:25:05 papaya org.gnome.Shell.desktop[18687]: (EE) Segmentation fault at address 0x20 dets 19 21:25:05 papaya org.gnome.Shell.desktop[18687]: (EE) dets 19 21:25:05 papaya org.gnome.Shell.desktop[18687]: Fatal server error: dets 19 21:25:05 papaya org.gnome.Shell.desktop[18687]: (EE) Caught signal 11 (Segmentation fault).

I'm starting to detect a pattern that this crash only happens in multi-monitor situations. This Chrome instance is opening on the laptop screen and I had Hangouts video call open on the external monitor. You can see Chrome saying "Created new window in existing browser session." right before the crash. jaan 05 10:54:17 papaya chrome-mlcccdepafjjmjdkedhaegoncahjjnle-Profile_4.desktop[25006]: [25006:25006:0105/105417:ERROR:browser_main_loop.cc(243)] GTK theme error: Unable to locate theme engine in module_path: "adwaita", jaan 05 10:54:17 papaya chrome-mlcccdepafjjmjdkedhaegoncahjjnle-Profile_4.desktop[25006]: [25006:25006:0105/105417:ERROR:browser_main_loop.cc(243)] GTK theme error: Unable to locate theme engine in module_path: "adwaita", jaan 05 10:54:18 papaya chrome-mlcccdepafjjmjdkedhaegoncahjjnle-Profile_4.desktop[25006]: Created new window in existing browser session. jaan 05 10:54:18 papaya org.gnome.Shell.desktop[20281]: (EE) jaan 05 10:54:18 papaya org.gnome.Shell.desktop[20281]: (EE) Backtrace: jaan 05 10:54:18 papaya org.gnome.Shell.desktop[20281]: (EE) 0: /usr/bin/Xwayland (xorg_backtrace+0x56) [0x57cf36] jaan 05 10:54:18 papaya org.gnome.Shell.desktop[20281]: (EE) 1: /usr/bin/Xwayland (0x400000+0x1808c9) [0x5808c9] jaan 05 10:54:18 papaya org.gnome.Shell.desktop[20281]: (EE) 2: /lib64/libpthread.so.0 (0x7f67c1a4d000+0x10d70) [0x7f67c1a5dd70] jaan 05 10:54:18 papaya org.gnome.Shell.desktop[20281]: (EE) 3: /usr/bin/Xwayland (0x400000+0x15994c) [0x55994c] jaan 05 10:54:18 papaya org.gnome.Shell.desktop[20281]: (EE) 4: /usr/bin/Xwayland (dri3_send_open_reply+0x6d) [0x4e785d] jaan 05 10:54:18 papaya org.gnome.Shell.desktop[20281]: (EE) 5: /usr/bin/Xwayland (0x400000+0x29747) [0x429747] jaan 05 10:54:18 papaya org.gnome.Shell.desktop[20281]: (EE) 6: /usr/lib64/libffi.so.6 (ffi_call_unix64+0x4c) [0x7f67c1298020] jaan 05 10:54:18 papaya org.gnome.Shell.desktop[20281]: (EE) 7: /usr/lib64/libffi.so.6 (ffi_call+0x2f8) [0x7f67c1297a88] jaan 05 10:54:18 papaya org.gnome.Shell.desktop[20281]: (EE) 8: /usr/lib64/libwayland-client.so.0 (0x7f67c33d9000+0x8f3a) [0x7f67c33e1f3a] jaan 05 10:54:18 papaya org.gnome.Shell.desktop[20281]: (EE) 9: /usr/lib64/libwayland-client.so.0 (0x7f67c33d9000+0x5cf0) [0x7f67c33decf0] jaan 05 10:54:18 papaya org.gnome.Shell.desktop[20281]: (EE) 10: /usr/lib64/libwayland-client.so.0 (wl_display_dispatch_queue_pending+0x7c) [0x7f67c33dff3c] jaan 05 10:54:18 papaya org.gnome.Shell.desktop[20281]: (EE) 11: /usr/bin/Xwayland (0x400000+0x2390b) [0x42390b] jaan 05 10:54:18 papaya org.gnome.Shell.desktop[20281]: (EE) 12: /usr/bin/Xwayland (0x400000+0x181312) [0x581312] jaan 05 10:54:18 papaya org.gnome.Shell.desktop[20281]: (EE) 13: /usr/bin/Xwayland (WaitForSomething+0x1eb) [0x57b1ab] jaan 05 10:54:18 papaya org.gnome.Shell.desktop[20281]: (EE) 14: /usr/bin/Xwayland (0x400000+0x148e71) [0x548e71] jaan 05 10:54:18 papaya org.gnome.Shell.desktop[20281]: (EE) 15: /usr/bin/Xwayland (0x400000+0x14d198) [0x54d198] jaan 05 10:54:18 papaya org.gnome.Shell.desktop[20281]: (EE) 16: /lib64/libc.so.6 (__libc_start_main+0xf0) [0x7f67c16d1620] jaan 05 10:54:18 papaya org.gnome.Shell.desktop[20281]: (EE) 17: /usr/bin/Xwayland (_start+0x29) [0x422ff9] jaan 05 10:54:18 papaya org.gnome.Shell.desktop[20281]: (EE) jaan 05 10:54:18 papaya org.gnome.Shell.desktop[20281]: (EE) Segmentation fault at address 0x28 jaan 05 10:54:18 papaya org.gnome.Shell.desktop[20281]: (EE) jaan 05 10:54:18 papaya org.gnome.Shell.desktop[20281]: Fatal server error: jaan 05 10:54:18 papaya org.gnome.Shell.desktop[20281]: (EE) Caught signal 11 (Segmentation fault).
