Thanks sergei

I wouldn't even mind the faint smoke that is there,
if it showed up at all!
And another bundle of little errors/omissions/glitches to throw into the mix.
1)
On the compact TAI, distance indicators are way too tightly packed to be usable, especially when making lines of a horizontal nature:
On a vertical line it's just acceptable.
On the maximised TAI map, or on the main nav map, the spacing is absolutely fine for any angle of line.
2) With some regularity (maybe 1 in 5 times),
when I select the UZO, I'm given a 1x zoom display, and a double-overlay - a kind of combination of the UZO sight and the periscope sight. Here's an example looking back at the WO standing next to the UZO itself:
If I roll the mousewheel up, it zooms in and gives me the regular UZO sight (after which I can't zoom back, which is correct).
3)
When trying to run decks awash (even described in one of the loading screen tips!),
the boat is considered to be 'underwater' (as indicated in the top-right), yet the basic depth meter shows we're still surfaced, and I am able to walk around on deck. The watch crew have all disappeared below and I also can't open the hatch to get into the boat, unless I issue the 'surface' command first.
Perhaps the threshold for what is considered 'submerged' and what is considered 'surfaced' could be altered.
I know, this behaviour was the same in SH3, but would be nice if had been given proper consideration, especially considering the game tip on the loading screen.
I set decks awash by using the advanced depth control and ordering 6-7 metres. To enemy ships' sensors, it probably considers me underwater, so could be a minor exploit.
4)
In the Conning Tower, the compass is inactive. Moreover, the inner 10° dial is missing, in place of a speed dial texture! In either case, none of the two discs move at all (I know the boat is heading roughly north in this example, and the compass shows north, but that's just coincidence):
It's a shame, as all the other compass dials throughout the boat seem to work correctly (including the inner dials), which is excellent to see
Oh, the clock in the conning tower is another for the list of broken clocks. Always shows 12 o'clock.
5)
No engine sound when at All Stop with one engine running to recharge battery. The right dial shows a constant 500rpm when the batteries are recharging, but at all stop no engine is heard running, and they are both seen stopped if you take a walk to the engine room.
Since the left propeller doesn't run when recharging batteries, I'd assume the left engine would be the one that does the recharging - are the dials the wrong way around? (I'd expect the left dial to be for the left engine!)
Oh, and back to the Conning Tower - the two tachometers don't function at all in there, but no big deal really.
6) This doesn't always happen, but the TC dropped down to 1x, telling me something was about to happen. On the bridge I hear the sound of aircraft, they fly right overhead (2x Hurricanes), but at no point do my crew even notice them - see event log in lower-right.
The other issue of aircraft not attacking is already well reported.
7) This is a
very minor cosmetic complaint. In fog, there's a kind of grey 'layer' over the whole screen, reducing the contrast to give the feeling of poor light and mist (blacks turn grey etc.). But the boat's interior still appears to be vivid and not washed out by the effect. It's probably a limitation of the game engine, but I find it a little ugly

:
I think the nearby crew members look a bit too washed out given that they're only a couple of metres away (the fog isn't
that thick), but if it wasn't for the view down the hatch it would look fine.
I can live with this, obviously
The game is still bloody gorgeous in every way

Today I just noticed the subtle 3D wake from my sub when running 'Ahead Flank'. I watched those little curved waves trailing behind me for a good few minutes, in awe.

Also noticed the constant 3D bow wave generated by a DD as it ploughed through the sea.
