LyX does not "instant preview" the math equations anymore. It did, before. I do not know what I did that caused this behavior. I think, LyX 2.5.1 was able to instant preview the equations, but not sure.When I enter into an equation editing box, and go out momentarily, the instant preview works on that specific equation. When I exit LyX and reopen, the same cycle repeats.I am betting that this is related to either updated permissions of Windows 11, updated TexLive, some issues with the LyX cache or smtg similar.I will see if I can fix it by myself, but I want to know if anybody else experience a similar issue, and what would be suggested checklist of actions on this?Baris
Answering my own question:Seems like if an equation is put into an landscape environment along with some other formatting command, that specific equation locks the instant preview of the whole document:
\begin{landscape} \vspace*{\fill} \resizebox{\linewidth}{!}{
$\setcellgapes{9pt}\makegapedcells\ensuremath{
\global\long\def\arraystretch{2.2}%
\begin{array}{cc}
a & d\\
c & b
\end{array}}$
}\vspace*{\fill} \end{landscape}
See the attached MWE.
