I read the bug text and looked at the images.
Quote: "The checkbox at the bottom saying "Groß/Kleinschreibung" (case sensitive search) is misaligned at the top of the search&replace bar. It should be aligned with "Alle suchen" (search all) in the middle."
I was wondering if the text and the icon to its right are aligned, where the text is not centered in the space but is formatted to be aligned with the top of the " footer toolbar cell".
I cannot easily test this bug, since the only Win10 computer that has a video card for 1080p is no longer connected to my 1080p TV/Monitor. I have a 720p TV/Monitor attached to it. I am typing this email from a Linux system with 1080p monitor.
Could you please send me/us information about what version of LibreOffice you are running and what extensions are installed that gives you the search toolbar[s] that are the alignment issues. I do not have those options on my version of LibreOffice [either Win10 or Ubuntu Linux]. I run versions from 4.2.8 through 5.0.2[?], though I plan on upgrading the 4.2 to a 4.4.x version till 5.0.x gets to 5.0.3 or .4.
