Plater tab crashes on ubuntu

[subsite]

Version

1.40.0-beta+linux64 (Run from AppImage Slic3rPE-1.40.0-beta.linux64-full-201805231653.AppImage)

Operating system type + version

Ubuntu 18.04

Behavior

• Describe the problem
  Control panels aren't redrawn when switching back to the plater tab (see screenshot). It still responds to clicks if you click the area the button normally is. This problem first appeared with 1.40.0-beta, 1.40.0-alpha still works normally.

When run from the terminal, it gives the following output (The IA__gtk_color_button_set_color-error displays immediately on startup, the IA__gdk_window_thaw_updates appears when the bug is triggered):

$ ./Slic3rPE-1.40.0-beta.linux64-full-201805231653.AppImage 
Creating main frame...

# ...and the same error repeated numerous times

• Steps needed to reproduce the problem
  This happens after changing some parameters in another tab and then trying to return to the Plater. For me, this can be reproduced by opening the Filament tab and then selecting one of the sub menu items (e.g. Cooling).

Hi. You might wanna have a look at #898

Please, report if that helped to solve the problem.

Thanks, it seems to be the same problem. However, the mentioned workaround doesn't apply any more, as Ubuntu is now stable at 18.04 Bionic and is no longer using Unity as its desktop environment (they moved back to Gnome). The tweak to disable overlay scrollbars doesn't seem to be available in the tweak tool any more.

I will keep looking for a similar workaround for 18.04, but it would be nice if Slic3r were usable without changing the look and feel of the whole operating system. I'll have to move back to 1.39, but I'll really miss all the nice features of 1.40.

Ok, I might have found a similar workaround for 18.04.

In a terminal, enter gsettings set com.canonical.desktop.interface scrollbar-mode normal

I added this to the https://github.com/prusa3d/Slic3r/wiki/Known-Issues-and-Solutions

Awesome, thank you very much. Since you found a way to fix it and there is apparently nothing else we can do about it (if the bug is in Ubuntu itself), I will close the issue, if you don't mind. If you do, reopen it at will. Thanks again for your feedback.

No problem, we can close this. Thanks!

Fixed in Slic3r 1.40.0 final release.
