Dialogs in Fedora installer partitioning tool sometimes do not respond to mouse input (Fedora 39, GNOME 45)
This is an upstream report of https://bugzilla.redhat.com/show_bug.cgi?id=2239128 . It seems rather similar to e.g. #2918 (closed) and #2117 (closed) - which were both to do with mutter surface tracking - so I'm assuming this is in the same area.
The bug manifests when running the Fedora installer on the Workstation (GNOME) live image, and using the "advanced custom" partitioning option. When the 'advanced partitioning' UI opens a dialog - e.g. to show partition information, or provide formatting information for a partition, or something - sometimes that dialog cannot be interacted with using the mouse. Keyboard interaction works OK.
The bug doesn't happen every time, and the incidence seems to vary from person to person (so there's probably some relationship to system performance, or something). However, everyone who's tried has reproduced it at least sometimes (that's four different people so far).
To reproduce, download e.g. https://kojipkgs.fedoraproject.org/compose/branched/Fedora-39-20231004.n.0/compose/Workstation/x86_64/iso/Fedora-Workstation-Live-x86_64-39-20231004.n.0.iso , boot it, run the installer, click Installation Destination, ensure a disk is selected, click "Advanced Custom (Blivet-GUI)", click Done, right-click an existing partition (create one first if there isn't one), click Information. See if you can click the Close button on the resulting dialog. If you can, try it a few more times. Maybe try with not the right-most partition (as lruzicka suggests).
For me, in a quick trial, it fails about 50-60% of the time in a VM with an existing three-partition layout, using the second partition to reproduce.
Unfortunately it's a bit difficult to get debugging information when the bug happens in the installer like this, but I'll try.
