Forgot to mention: When I have this problem, I often can surround it by doing a new OCR'ed version of the PDF.
Disregard my previous post. The problem is back in Skim, but not in preview.
I had this erratic behaviour too after update to MacOS 26.2, in any app. It turned out to be caused by Bitwarden's hardware acceleration, and turning the hardware acceleration off solved the problem.
Table fonts size >18 creates overlapping notespanes and search results pane.
Skim 1.5.1 Crashes when hiting Edit Bookmarks
1.4.34 (108) Forget it, starting up both 1.4.33 and 1.4.34 at the same time triggered something. Search is working.
oh sorry typo error, the problem started after latest update to 1.4.34
Edit>Find>Search PDF I did update from 1.4.33 I did a normal search in the PDF, a part of my normal workflow, it returned nothing. It is not working in any of those PDF, were it should work. Went back to 1.4.33
