Elements 2019: Polygonal lasso not working with high resolution display

Now that I have a 4K monitor, the PSE polygonal lasso won't start (ignores initial click) in roughly the upper 25% of the display.  If I reduce screen resolution vertically, to 1440, it works everywhere.  I searched the forum and see posts about this problem from up to 5 years ago,  so it seems there's no point reporting it as a bug, but is there any other workaround?   I just upgraded from 15 to Elements 2019 and that didn't help.  Windows 10, and yes I have a supported video card with the latest driver.

In Elements 2018 this problem started for me when I upgraded to a 4K (3840 X 2160) monitor. The polygonal lasso tool will not work at all in the upper part of the image and tends to auto-complete prematurely elsewhere. I found 2 things helpful: 1) Switch back to 1920 X 1080 resolution apparently fixes it; 2) This seems to get it working in 4K mode: Edit > Preferences > Display & Cursors > Set UI scale factor to 100% > Exit & Restart program. It makes the menu text quite small, though.
