Odd Behavior with Cura 2.5.0 Layers Slider

[phamtq 0]

When I load up an .STL file and have Cura slice the object, I get an odd behavior with the layers slider when I'm in the Layers View Mode. Using the top slider makes all the layers disappear and all I get is the transparent view of the model. Using the bottom slider and sliding it upwards creates the desired effect until you get to a certain point and then it skips to a lower section of the layers. I've included a link to an Imgur album here so you can see what I'm talking about.

I'm running Cura 2.5.0, on a Linux distro (Arch Linux), using Gnome 3.2 for the desktop environment. I have a Radeon R480X so I don't think it's a matter of having enough hardware to render the layers.

Has anyone encountered this problem?

Weird. Do the logs say anything interesting?

Weird. Do the logs say anything interesting?

 

There doesn't appear to be although this entry:

 

2017-05-23 06:56:29,830 - ERROR - UM.PluginRegistry.loadPlugin [91]: Plugin VersionUpgrade24to25 did not return any objects to register

 

might be relevant. The rest of the 'ERROR' entries I get in the log appears to be connected to 3MFReader, Savitar, and UM3NetworkPrinting.

Here are the entries in the log labeled ERROR:

Here's a link to the complete log if you or anyone else wants to take a look at it: Pastebin.

Also, I started my Windows 10 partition and installed Cura 2.5. Everything works there. Thinking that this might be isolated to just Arch Linux, I installed it on my notebook with a Intel HD Graphics 3000 and I could step through individual layers (although not ranges of layers). This seemed to put it in some kind of "compatibility mode".

[ahoeben 982]

Those errors aren't very - let's say - charming that they occur in that way, but they do not influence layerview. The first error is because of a workaround, and just means that one of the upgrade plugins is skipped. The other errors are because some python modules are missing: libSavitar and python-zeroconf.

I get the same odd behavior when using the layer view mode.

I'm using Cura 2.4 in Arch Linux. KDE desktop environment. My computer is using an Intel Haswell GPU.

[sols64 0]

Got the Cura version wrong. I'm also using Cura 2.5.0 on arch linux.

When booting Ubuntu 17.04 on the same computer, the layer mode view works fine on Cura 2.5.0.

Just downloaded Cura 2.6 Beta and the problem is gone. I installed 'appimage-git' from the AUR and ran './Cura-2.6.0-BETA.AppImage'. So whatever got changed with the layer view in 2.6, fixed this too. Hopefully the changes remain and are fixed in the 2.6 stable release.

Hi there,

Just downloaded Cura 2.6 Beta and the problem is gone. I installed 'appimage-git' from the AUR and ran './Cura-2.6.0-BETA.AppImage'. So whatever got changed with the layer view in 2.6, fixed this too. Hopefully the changes remain and are fixed in the 2.6 stable release.

hm, I think a newer Version of Cura does NOT fix the problem...

look at this thread (scroll down): --->

(my PC is an old one, Win7 / dual Core)

@ phamtq :

What about this 'appimage-git' ? how does it work?
