I'm thinking heat distortion more than electronic shutter distortion, which I don't think should be an issue with static subjects.

Originally posted by Breakfastographer Yes, definitely thermals. You did not lose anything, the image wasn't sufficiently sharp to start with. Pixel shift can't fix that.
I think it's not thermal, because it's one of the panorama shots, so if it's really a thermal issue, then all my images that were shot that day will suffer from that, but no, this was the only one.
Also the part that I cropped was an out-of-focus area, so it might not be very sharp, but the weird distortion is across the frame.

I don't think it's due to atmospherics. The EXIF shows focal length as 50mm, so the building can't have been far away.
It looks very much like one of the images has lens distortion correction applied, and the other doesn't
I'm wondering if there might be a bug in the version of RawTherapee the OP is using.
@syyrmb - would you be willing to share a copy of the file for us to investigate? If so, I could give you access to my Google Drive to host it...
Also, have you tried to process the photo in PDCU?
I‘d say the building is at least 500 meters away from me.
I just tried to disable lens correction in RT, no effect, still the same, and I believe the distortion is in the image for my experiment with DCU below.
I uploaded my file to there:
IMGP1415.zip - File.re temporary file sharing
(please only use it for studying purposes)
After hearing your suggestion, I tried DCU and disabled motion correction, image shows motion artifact and blurs, which shows that the distortion is inherited in the image.
