this happened to me too, in both list and previous verison

[podraco]

i believe that the preview should size up the images before showing them, do not load anything over 5 MB would help and also, use an item list (that recycles the widgets) to avoid that canvas over load

[Sahil-pixel]

and what about button icon ? button icons are not appearing.

[Sahil-pixel]

please fix these problems ...as soon as possible

[podraco]

There's a pull request that modify a all the button.py script, it hopefully include the fix for a missing icon, mostly of it's not inside the icon definitions it will be assigned as icon = "help"

[MS-Jahan]

Facing the same error when preview=True. Otherwise, working great.

[aidingh]

Is this problem fixed? Iam having the same issue? Would be great to solve soon? I could help out if needed. Because the preview mode is a nice feature for the mobile app we are creating

[HeaTTheatR]

@aidingh Not yet fixed.

[runette]

Having these problems but NOT in preview mode - and importing MDFileManager into my project seems to have polluted other non-related instances of ModalView to have the same problem. Very confusing. - but all related to White Screen and Exception: Cannot push more than 128 level of stencil. (stack overflow)

Can you update kivy to 2.0.0? @Sahil-pixel

[Sahil-pixel]

@Neizvestnyj There are bugs on mobile devices.

@Neizvestnyj There are bugs on mobile devices.
