[Bug 2316236] New: slic3r no longer opens properly and cannot manipulate stl images

https://bugzilla.redhat.com/show_bug.cgi?id=2316236

Bug ID: 2316236
           Summary: slic3r no longer opens properly and cannot manipulate
                    stl images
           Product: Fedora
           Version: 40
          Hardware: x86_64
                OS: Linux
            Status: NEW
         Component: slic3r
          Keywords: Regression
          Severity: high
          Assignee: [e-mail]
          Reporter: [e-mail]
        QA Contact: [e-mail]
                CC: [e-mail],
                    [e-mail]
  Target Milestone: ---
    Classification: Fedora

Since upgrade to kernel 6.10.10 or 6.10.11 and other packages updated at the
same time slic3r has a distorted display when first opened.  Resizing the
window, even a tiny amount, restores the display properly.

When opening any stl file for use to create the gcode that image is no longer
manageable.  The image cannot be selected with the mouse and functions that
depend upon having the image selected are not usable.
This includes scaling, cutting, creating multiple copies, rearranging on the
printer deck, rotating, etc.

Reproducible: Always

Steps to Reproduce:
1.open slic3r and attempt to use if to create gcode for use with a 3d printer.
2.
3.
Actual Results:  
images, once loaded into slicer cannot be manipulated in any way

Expected Results:  
The image displayed should be able to be selected then the functions for
scaling, rotating, creating multiple copies, and rearranging on the bed for
proper printing should all function as previously done.

I am using fedora 40, kernel 6.10.11, Workstation and slic3r has been working
well until the last few updates.

I have also downloaded the slic3r code and compiled it locally but the locally
compiled version works the same as that installed with the rpm file. dnf list
installed slic3r gives this ."slic3r.x86_64   1.3.0-33.fc40     @fedora"

same stl file after clicking on the object

After clicking on the object in slic3r it should be selected and turned green
The functions on the tool bar that are greyed out should become active and
there should be a right-click menu available.  The object cannot be selected so
cannot be manipulated in any way.

When you reboot your system, you should be able to select an older kernel. Doe
that make slic3r work again as expected?

On fedora 40, when opening slic3r with any available kernel between 6.10.9 and
6.10.12 the reported error is seen.

I installed a VM with f39 and fully upgraded it.  
On f39 slic3r works properly with all kernels including the latest, 6.10.12

It appears this regression appeared with the upgrade between fedora 39 and
fedora 40.  
As such it seems that some supporting dependency may be a factor.

Note that on Fedora 41 Beta I find that slic3r again works in every apparent
way EXCEPT the initial setup wizard when slic3r is newly installed and opened
for the first time does not function.  I was able to use the settings and
configure it, but the wizard fails.

I suspect the failure of slic3r is because of the changes in python between
fedora 39 and each fedora release since.
Python 3.11 on fedora 39 is changed with upgrades to python 3.12 and 3.13.
If slic3r is not actively maintained to remain current with python upgrades it
would be expected to fail at some point.

Slic3r does not use Python.

This message is a reminder that Fedora Linux 40 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora Linux 40 on
2025-05-13.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained. At that time this bug will be closed as EOL if it remains open with
a
'version' of '40'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, change the 'version' 
to a later Fedora Linux version. Note that the version field may be hidden.
Click the "Show advanced fields" button if you do not see it.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora Linux 40 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora Linux, you are encouraged to change the 'version' to a later version
prior to this bug being closed.
