Thanks a lot for the answer. I guess that the problem is more related to my
hardware which is not very modern... or?
As you can see in the attachment "test setup", with the modification of the
skia settings, in fact, the problem seems solved (with both settings changes)!

ok. it just seemed strange to me that with the same pc it didn't happen before
(with the previous releases)

Ok !!! I understood! ;-)
I'll do some more testing in the next few days, but I think I'll use this
setting you suggested: "You can change to the software raster mode by the
checkbox 'Force Skia software render'".
One last question: to me as an end user, something changes in terms of usage or
speed of l.o. using, or not, skia in its different ways?
What changes for me in practice?
Am I losing any advantage?
