This bug appears to have been reported against 'rawhide' during the Fedora Linux 42 development cycle.
Changing version to 42.

Comment 4 Pierre Ossman 2025-03-24 08:04:32 UTC

Awesome!

TigerVNC will need a rebuild for this to take effect. Can that be queued up as well?

Comment 5 Fedora Update System 2025-03-31 02:35:50 UTC

FEDORA-2025-9bf140aab2 (fltk-1.3.11-1.fc41) has been pushed to the Fedora 41 stable repository.
If problem still persists, please make note of it in this bug report.

Comment 6 Pierre Ossman 2025-03-31 11:13:19 UTC

I can confirm that the current tigervnc package (tigervnc-1.15.0-2.fc41.x86_64) still doesn't have working back and forward mouse buttons.

Comment 7 Brian Morrison 2025-03-31 15:35:26 UTC

The fltk-1.3.11 packages for Fedora 42 appeared in the last couple of days, maybe you need those on your F41 system.

Comment 8 Pierre Ossman 2025-04-01 12:23:32 UTC

fltk is upgraded on my system:

> $ rpm -q fltk
> fltk-1.3.11-1.fc41.x86_64

But that is not sufficient. TigerVNC must also be rebuilt with the new fltk-devel.

Fortunately, it may resolve itself via bug 2356047, which will require a new TigerVNC package to be pushed out.
