from today on I got some problems with the display of Smath.
Working on the SMath 98.6484 (unoffial, portable with maxima plugin). I had a similar problem right from the start whe i used this version (in february). The problem could be solved by deactivation a plugin (image region).
But from today on, I got the problem again, even so I didnt acitvate this plugin.
I guess something changed with the last update of win 10 (they didnt ask ;-) -> windows-style ;-)).
Image region DPI issue was fixed 7 months ago.. It works well on my WIN10 machine. Try updating to latest? https://en.smath.info/forum/yaf_postsm44313_Editable-Image-Region---Plugin-Update.aspx#post44313
Well, I already installed the newest version, which is supposed to contain the newest plug in version (as on the link you sent me) (https://en.smath.info/forum/yaf_postsm44313_Editable-Image-Region---Plugin-Update.aspx#post44313), but still the same problem.
