After using the Qt5 build for one week, here are some minor problems.

1. Whenever an item is selected in the Fiducial/ROI/Ruler tool, the items get duplicated to an certain number of items that I didn’t count.  
 ![Screenshot_20170826_130740](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/f/f/ffa89445d8ab2550bf6afb8aa8a380eced2c674b.png)

2. In Volume Rending module, the items of the ‘View’ combobox are no longer checkable.  
 ![Screenshot_20170826_130856](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/0/f/0f53338b31288eca77f18452a785b3a736ff594f.png)

3. Switching to module ‘SceneViews’ crashes Slicer :

- _Switch to module: “SceneViews”_
- _qSlicerSceneViewsModuleWidgetPrivate::setupUi - Capture link not implemented with Qt5_
- _qSlicerSceneViewsModuleWidgetPrivate::setupUi - Restore scroll bar position not implemented with Qt5_  
As it says, it has yet to be implemented.

All these are found on today’s build after ‘git pull’ (2017-08-26).

I think developers might be interested in this post.

Regards.

Thanks a lot for reporting - it’s very useful. I’ve added these issues to the [Qt5 migration lab page](https://www.slicer.org/wiki/Documentation/Labs/Qt5-and-VTK8#Slicer).

May I report one more crash source with the QT5/VTK8 build:

Any tool in the _new_ segment editor crashes Slicer as soon as the corresponding button is pressed. The old segment editor is still functional.

Best.

Thanks. But when I click on ‘Show details’ as per attached image, Slicer crashes immediately.

Thanks for testing! Unfortunately I cannot reproduce this, as I only have a Windows build with Qt5. I’m building one on Mac now and see if it can be reproduced there. In the meantime @Davide_Punzo Can you please try to see if this is as easy to fix as the previous one? Thanks a lot!

Slicer crashes in Threshold Scalar Volume on ‘Apply’, if ‘Below’ a threshold value is selected. It doesn’t crash if ‘Above’ or ‘Outside’ is chosen. Using Qt5/VTK9 build on Linux.

@hherhold I’ve started a Mac build (although it’s 10.13.1), will let you know how it went.

@chir.set I wasn’t able to reproduce the crash with either way, but I tried on Windows. If anyone uses Linux for development, please test this one. @jcfr could you try? Otherwise I’ll need to do a build on a VM. Thanks!

Thanks to @adamrankin, the issue related to VTK hierarchy stamps file should be fixed in [r26834](http://viewvc.slicer.org/viewvc.cgi/Slicer4?view=revision&revision=26834)

> ArchLinux … Any tool in the new segment editor crashes Slicer as soon as the corresponding button is pressed.

I am not able to reproduce the crash.

If this is still an issue, setting up a VM may be the best way forward.

this was fixed in the past in [Dual 3D mode: loading a scene with a single view node, second view is uninitialised · Issue #819 · Slicer/Slicer · GitHub](https://github.com/Slicer/Slicer/pull/819) and [https://github.com/Slicer/Slicer/commit/0c3f2cca8d11ed49d55724bca9ca166b08309d0d](https://github.com/Slicer/Slicer/commit/0c3f2cca8d11ed49d55724bca9ca166b08309d0d)

Instead I confirm this one:

> [@chir.set](#):
>
> Slicer will crash on application exit if the ‘Standard Quantitative’ pane has been shown, whether it is shown or not on exit. Using Qt5/VTK9 build on Linux.

Sorry, but I didn’t understand this other one:

> [@chir.set](#):
>
> Slicer crashes in Threshold Scalar Volume on ‘Apply’, if ‘Below’ a threshold value is selected. It doesn’t crash if ‘Above’ or ‘Outside’ is chosen. Using Qt5/VTK9 build on Linux.

In addition the linux version (at least my build)

1. some & still appear in the comboboxes and icons in modules and views seems much smaller

Thanks Davide! Was the module name in the module selector like this before (“Se&gment Editor”)?

you are welcome! the & issue (it shows in many places like the module menu, titles in plotting views, etc. ) was present before [https://github.com/Slicer/Slicer/pull/864](https://github.com/Slicer/Slicer/pull/864)

The smaller icons (?), menu misalignment (ctkCollapsiblegroupbox?) and smaller ctkCollapsibleButton are a result of the new style set in [https://github.com/Slicer/Slicer/pull/864](https://github.com/Slicer/Slicer/pull/864).
