In Inkscape,when I click and drag from the ruler, I expect to see blue guidelines appear which I can then position, and later reposition by clicking on them, and get more detailed control through a dialog that opens when I double-click on them. What actually happens is that red guidelines appear briefly, and then the whole window moves. The red guidelines remain, adjacent to the ruler, but I can’t click or double-click on them. It gets weirder.
I have 2 laptops and a bootable USB that exhibit the same behavior. They’re set up in similar fashion with KDE, but use different appearance settings (color, plasma theme, icons/cursors). A bit of googling suggested that this problem can be the result of the selected gtk theme under kde, but I tried changing these to no avail. I also installed xfce (which is based on gtk like inkscape) and icewm, same behavior there.
If I go into system settings and return the theme to opensuse default, no change. However, I can create a new user account, and the problem doesn’t happen, even in kde. If I go back to my main user account and run inkscape as that other user (or run as root), it works correctly a couple of times and then the erroneous behavior starts on the third time I start inkscape.
Figuring I had messed up some setting, I deleted ~/.config/inkscape, but it made no difference.
So, I can create another user account, set up everything the way I like it, delete my original account and probably be happy, but I’m afraid that since I don’t know what caused it (on all 3 installs), it could come up again. So any ideas as to the root cause? Has anyone seen this before with plasma 5.17?
I’m not sure when the problem first occurred, because I only just started working my way through inkscape tutorials.

PS: Same results with inkscape appimage.
