 I noticed something odd with water reflections this morning. It's hard to describe but I'll give it a go and try to provide a couple of screen shots.
When on the ground i.e. not flying, reflections seem to track with the camera instead of staying fixed to the item they are reflecting. If one merely flies, even close to the ground, the reflections snap back to their correct position. Once on the ground, they rotate with the camera once more. On the ground: https://gyazo.com/95cd720f97111ac6e2b2c91094b326b8 In the air: https://gyazo.com/cece86886c49a27b781b935817e6d572 I'm using EE (no culling), All Shadows, All avatars and objects reflections plus various things like SSAO. I can provide my settings if helpful. Other light and reflection combos seems to exhibit the same behavior. Info:

The screen shots you provide are not visible by me (gyazo.com does not use standard HTML5, obviously, and probably expects Chrome or nothing, meaning none of my browsers can use it)... Please, post on another site or inside a zip file here.
What happens if you disable the "Cull water" setting (select "Never (fastest)" in the combo box of the "Preferences" floater, "Graphics" tab, "GPU features" sub-tab) ? |

Sorry about the links. I don't use that tool very often so maybe I did something wrong.
I have converted to JPGs and attached here. I hope the detail is still visible for you as they were taken at night, though that isn't relevant to the issue. As far as Cull Water, I have been using "Never (fastest)" for a number of weeks now. But having said that, I didn't test with other values. If I use any of the other 3 values, the issue does NOT occur. It only occurs when set to "Never (fastest)" in .51. It does not occur in .50. *Edit: Further testing shows that turning of "Enable object-object occlusion" also prevents it from happening, even with Cull Water set to "Never (fastest)".

Your pictures are so dark, that I had to gamma-correct them like mad to see anything...
 This is very strange, because I cannot reproduce this here, and a change in LL's viewer (backported in 1.28.2.51) was precisely supposed to solve that issue (that did exist before)... The fact you are not seeing it while flying is likely due to the fact that I got a work-around for it (I already observed in the past that flying up/down straight was causing such an issue, and implemented the work around for flying avatar), that I forgot to disable for the EE renderer after applying LL's fix. I also spotted other parts of the code that could need changes, and came out with the following patch:
If you can compile the viewer yourself, please try that patch and let me know if it solves the issue for you. |

You can look at the page source for the direct picture URL, it's close to the top of the source. With Firefox -> ctrl-U, then look for this header (or a similar one):
Or you can try direct input adding a few bits in the original URL (using one from this thread for example, compare with above): https://i.gyazo.com/95cd720f97111ac6e2b2c91094b326b8.png Experience might vary depending on file type of course, in that case page source is helpful. I had to figure it out since people send way too much gyazo all over SL  |

When/if gyazo.com decides to become compliant with official and widespread standards, and thus becomes compatible with all browsers, then I may perhaps start to use it. Until then, they can go fuck off !  Life is too short to loose your time with total suckers. Period. |

Those 30 seconds it takes (with keyboard shortcuts) can be worth it the day you are stuck in a catch 22 with people insisting on the old recurring "but it works for me".  I have been there, done that, several times by now. So that's why I shared the workaround in case it would help someone at some time... 
I spent some time digging through their support today (while I waited for other things to finish, so no lost time on my account) and found their blog post about browser support, and I'm totally siding with you Henri as they claim to redirect unsupported browsers directly to the image in question, which does not work of course.. 'nuff said. |
