Looks to me like you were using the electronic shutter, combined with the frequency of the fluorescent light this results in only parts of the photo getting illuminated by the lights. You may prevent this either by using  lower shutter speed (<60) or the mechanical shutter.

I have been a Canon user since the AE1 Program, T90 and eventually EOS series film then digital. Currently have two Mark 3's and L glass. My kit was so heavy and i just didn't use it unless I was being paid. CPS is great and I am thankful for that system. I am a new convert to Fuji I have the X-T1 and the 23 and 56 and I carry it every where. It light, inconspicuous, super sharp, great colors. Starting shooting JPEG and I love it. Recently my wife and I did an engagement session she shot Canon with 135L glass I used the Fuji. Her in focus keeper rate was much higher. But I got crazy photos with different angles I would never get with the canon because I would be hugging the earth or hoping I could compose the shot. I love the articulating screen. It's the cats meow. I feel like the focus system is good, and i can't wait for the update. I wish they were keeping with original rumored date as I have a wedding that weekend and would love to use the camera with the improved focus system. Anyway I love my X-t1 and if I could suggest only one improvement it would be a locking mode dial. I am hard on gear and that mode dial get switched to double exposure or toy mode and it frustrates me. I love the the system. I love the community. I can't wait to see where Fuji goes next.

I've already said "Thanks" a number of times with my credit card.

I'm not an X-T1 owner, but can easily relate. I never really got into digital photography, which doesn't mean I was a big film shooter either - but I used to shoot and have a lot of fun during school days with my old film SLRs. Used to have a few digital point and shoot cameras, never liked them much, never got interested in buying a new one, always hated big clunky DSLRs. Until I saw a used X100 and just had to buy it, love on first sight. Since then I had so much fun getting back into photography and trying new stuff, it's insane. Not everything is golden in Fujiland, but for that I'll always be thankful. 

What a nice thread idea... we are often used to criticize Fuji on many different aspects. We need a new firmware, we desire more (or less) megapixel, we want more (or less) dials, we miss this (or that) lens, we pretend smaller (or bigger) cameras.
 
But we often miss the wood for the trees... and overall the system is just amazing, and just fun.
 
A few years ago, I was walking, alone, along the lonely northern cost of Bulgaria, sleeping in my tent or in caves. I had a heavy DSLR's system with me, and after days of walk under the sun I understood: I need it smaller & lighter. Luckily the CSC system just hit the market, and I immediatly switched to it. Olympus, then Panasonic, flirted with Sony, but in the end I stumbled on the Fuji X System, loved it, and opened FujiRumors.
 
What a relief... what a fun. And I discovered not to be alone. In fact, back in 2013 I wrote my "Thank You" to Fujifilm on FR here, also based on all the emails I received from FR-readers.
 
"Whoever enters the X-world seems to be happy with this decision. Wow, quality, passion, freedom, fun, inspiration, lightness… this, and much more, is what I read in your emails to me. If I should judge from your words, your emails, all your switch stories, well, I’d say that the X-virus can’t be stopped. But Fujirumors may not be the best place to judge the success or not of the X-series.
 
It’s just, I feel it in all your emails… it’s the excitement of (re)discovering photography, the fun to be creative with your camera… it’s the technology that meets our passion by combining vintage design and manual controls with top-notch digital image quality, it’s the dedication of Fujifilm to its customers.
 
Yes, we are (still) a small niche, but a pretty happy one :)"
 
So I join now and say "Thank You" to Fuji. I know we X-shooters have high expectations and that we can sometimes complaint about details. I love it how you listen to it and take it seriously. But overall we are X-shooters because you brought back fun into our photography again
 
cheers,
Patrick... a very happy X-T1 owner
