I have similar issue as in this post: https://discord.com/channels/429247498016653312/1104452291769151570
However my GPU is not on-board Intel, but an old nVidia Quadro FX 380 LP.

Game version: 1.11.20 & 1.12.6
OS: Win 10

Steps to reproduce:

open any map
zoom in and out

Wrong behavior:
Tracks and switches change color (or transparency?) depending on zoom level. Switches look misplaced. Game looks fine only at minimum and maximum zoom. Anything in between makes the game practically unplayable.

Expected behavior:
Tracks and switches stay visible regardless of zoom level.

Map:
any (map used in attached video: Round-And-About)

Troubleshooting:
I tried changing resolution and window mode, turning off all effects, updating GPU drivers and installing backwards (1.9.16) and devel (1.12.6) versions on Steam. The bug is NOT present in the older version. Both versions 1.11 and 1.12 act as shown in the attached video.

I am unable to reproduce the bug on another PC with a Radeon HD GPU.

#

could very well be just that the hardware is to "old" and uncommon. so it may miss some support for specific shader or something.

when I investigated that case, the available driver was several years old

@upbeat dock , what driver do you use?

But it raises the question why it was ok in version 1.10 and not in 1.11 and 1.12...

We upgraded Unity version and slightly modified the way how tracks are rendered. So either the the new version started using the unsupported GPU functionality or something new in track rendering started using it.

@granite monolith , maybe try to turn off 2d lights.

I've played with all settings, but the problem stays. As mentioned above the most likely reason is the change to unsupported GPU functionality for these older machines.

There are two older versions (10 & 11) under Beta. If i understand, update_10 should work for you

#

But the saves are not forward compatible so if you downgrade, new saves will not work.

Current driver is 342.00 from October 2016. I think the previous one was 341.95 from February 2016. All in-game effects are turned off.

Did you try buying new RTX 4090 and turn it on and off?

#

Jokes aside, I unftoruntatelly dont have a clue, what cause is doing this issue 😦

Yep, you are right, version 1.10.7 works fine. Last two saves of my endless Prague load successfully. Some of the previous saves work, some don't. It seems I was running different game versions on these two computers for a while. Well, I guess we can wrap it up by blaming Unity & old shitty GPUs. Now I have to actually work at my work PC, damn.
