I was running LO on a now old computer (Intel Core 2-6600, 2 Go, Windows-7 32 bits) successfully till branch 5.3 is released.
Then, with 5.3.2 and newer (up to recent 126.96.36.199) I faced a very, very slow performance, mainly on a display point of view. With Calc, move from one sheet to another in a folder needs seconds (sometimes >10) ; same problem when refocusing on the LO window ; I could see then repainting process in action for seconds.
Problem is similar with Write.
Moving back to LO 5.2.7 allows to recover normal performance.
Where am I wrong ?
