Anyone else been getting this? I've been seeing it on the Class 33, the Class 375 in MVL, the Class 465 and just now the 158 on MML. It's hard to describe or even show with a screenshot, but it's like a constant pulse of light fog on the window especially running off the edges. The only mods I have installed are the Riviera Lighting Pack and the Class 700 sound enhancement. The first has been in there for months and never caused an issue. The latter I installed after the Class 33 run which was displaying the artefact. Even when weather is set to very light fog, it never produced this constant pulsing of vapour rippling across and off the edge of the screen. It's highly irritating.
So definitely not one of my two mods, then. Looks like something slipped in a recent core update. Probably should have put my OP in GD as not many people tend to look at this section unless they are posting their own particular problem.
