Has U2020-10-16-2036 caused steam locos to emit technicolor smoke?

[copperpen]

It has for me, and in addition vitrually every surface of scenery and train have a speckly shimmer.

Video is Nvidia GT 1050

Not just the steam loco emmitters whose colors are wrong and garbled. Also note the oversized snowflakes. NVIDIA GeForce GT 710.

The same bug is in the previous update. I prefer to go back to the version from 13.10.2020
It has such a punk ambience ;-)

I also agree that 2020.10.13-0436 is the last version that has proper colours . The steam locos look like they're burning sulphur instead of coal and black steam from cylinders etc . for the later versions .

In U2020.10.16-2036 a new porting to Monogame has been introduced. I assume that this has created the problem. Also in the preceding porting to Monogame (the one in OR NewYear MG) this problem arose and was solved. IIRC the coding sequence of the colour components has changed in Monogame.

Will this be fixed soon?

Smoke color is still an issue in U2020.10.21-1851

Carlo, could you describe the fix you made for this issue?

[Csantucci]

I'm sorry, but I can't be of big help. At that time (October 2017) I used Tortoise SVN to update OR MG, and so I'm not able to get the story of the changes. I suppose that the problem has a relationship to this

that Peter already noticed and corrected for lights, but I'm not sure.
Here http://www.elvastowe...post__p__226424 I mention the issue.

If you read just subsequently in that thread, you will notice also the pixellation effect bug, that seems the same reported in another bug thread here.
Reading further in the thread, pixellation seems to have been solved here by Dennis http://www.elvastowe...post__p__228355 .
