An |attached| sequence number that is too old means that _cairo_xlib_shm_pool_cleanup() can call _cairo_xlib_display_shm_pool_destroy() and so shmdt() before the server processes the ShmAttach request, resulting in BadAccess errors. Similarly _cairo_xlib_shm_surface_mark_active() is called and uses XNextRequest() before the corresponding request, leading to similar races affecting _cairo_xlib_shm_surface_flush() and get_compositor() and _cairo_xlib_shm_info_cleanup(). I assume _cairo_xlib_shm_surface_get_obdata() has similar issues.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed.Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-bionic to verification-done-bionic. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-bionic.

Ubiquity also crashes inside a virtual machine (VirtualBox) running on a non-HiDPI host machine. I have observed corrupted graphics in the "main area" of Ubiquity when this bug occurs. By "main area", I am referring to the rendered rectangular area in Ubiquity below the title bar and above the "Copying files..." progress bar. The corruption looks like jagged diagonal lines or "snow".

OK, I can now reproduce the problem at scale=100%. The trick is to slow down the installer with GDK_SYNCHRONIZE=1.

Given that XShmAttach can fail (you can google the reasons), I think maybe we need to handle that in ubiquity/cairo and fall back to an alternative rendering method.

[Bug 1751252] Re: [regression] ubiquity crashed in debconf.py:104 with ValueError: invalid literal for int() with base 10: ''
Unfortunately I can't tell what in shm_access is failing exactly because gdb skips straight from shm.c:314 back to the caller. So that suggests this code path, but I can't verify it: static int shm_access(ClientPtr client, SHMPERM_TYPE * perm, int readonly) { int uid, gid; mode_t mask; int uidset = 0, gidset = 0; LocalClientCredRec *lcc; if (GetLocalClientCreds(client, &lcc) != -1) { // FALSE ... } /* Otherwise, check everyone else */ mask = S_IROTH; if (!readonly) { mask |= S_IWOTH; } return (SHMPERM_MODE(perm) & mask) == mask ? 0 : -1; } So Xorg _should_ be returning an error, and it is. The problem seems to be that the client (python3 gtk_ui process) has a real uid=0 and effective uid=999. So that allows it to connect to Xorg (normally Xorg rejects root clients), but doesn't allow Xorg to check the client shm permissions. So Xorg rejects the client's attempt at XShmAttach. How any of this relates to scale=200% and why it works at 100%, I'm not sure.
