Strange visual issues in 1.8.2.0

I have been having some issues with certain objects in openBVE 1.8.2.0. Mainly decal objecst such as train numbers and displays. 

For example, My side displays on my London Underground D78 stock train: 



The first screenshot shows the problematic right hand side display of the train. The main display box mesh appears to be in front of the glass when it should be behind it. The actual display text shows up as normal when far away from the train but when you get too close it disappears. 


Second Screenshot shows the Left hand side display of the trains which works as it is supposed to. Note the display is behind the glass and the text is visible.

This issues has not appeared in previous stable versions of openBVE.

This is happening for me as well, seems that the alpha channels are messed up. Not a problem if your train has coded windows in but if it uses transparent textures...

I tried different interpolation settings and no succeed.

In order to get a 100% GL3 renderer working (required for 64-bit on Mac), we needed to move the alpha test into the shader for the new renderer. (only- the old renderer should be correct)

I thought this one got nailed down :/

I tested the train in the old renderer of 1.8.2.0 and, as you said, it shows up properly as intended with no disappearing.

Please try the build from today.
I *think* I've found the issue, but it's mega complex to get right......

The aplha channel has bee na pain in the lower back for a while now. Especially in Route Viewer.
