As [robert.tomasik] disscused on this topics:
It seems that for some reason, in many installations of windows 10 64bits (not always) the program does not work, even reinstalling and testing with different JREs
I don’t have any third-party modules, I talk about clean installations all the time.
I have solved the visual problems like this:
setx J2D_D3D false
But it seems that there is some kind of problem with the management of the threads, the program starts normally, but all the options take many seconds or a minute to work.
I give a new case, it takes 40 seconds to open the window again, I give browse, it takes 30 seconds to open the file explorer, each folder to open, about 40 seconds. Still, it is impractical.
I have tried several different options for the Java VM. In the logs I do not see more than warnings, no errors.
I find it hard to believe that this only happens to 2 or 3 users, do you have any way to debug these errors?
