Same texture on same object in two different views not working correctly
Applying the same texture to the same object in two different views does not work. This may be related with this VTK issue (see conversation vtk/vtk#18121 (comment 902253)).
Steps to reproduce :
- Create a plane. Apply.
- In the
Displaysection, select and load a texture. - Open a new layout (or split the current layout) and select Render View.
- Display the previously created plane.
- Apply the previously loaded texture to the plane in this view.
- Select the first view again.
If the texture has an alpha channel, the plane will not be visible in the first view, with these warnings in the standard output :

[...]If a new plane is displayed in each view we have the correct behavior. Also if we load a different texture for each view then we also have a correct behavior.
Here's two image to test (one with transparency and one plain image) :
To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
