I started to use GIMP some years ago, and I was using 2.8.22 just to yesterday.
I did the same experience as dana_w with the newest release 2.10 and I confirm that many icons seam to be missing (perhaps, are they too small ? ), especially icons in various UI menus (Cut, past, preferences etc..).
I did any suggestion as rick2005 said in his reply and the final situation is a little bit better, but not completely satisfactory.So, if there are no other solution to this problem, I will go back to 2.8.22 and I will test sometime the new releases, to check if they are OK. Best regards,
Pici
