Description
Created attachment 362111 minimal example
Hello, I'm a developer of RawTherapee (http://rawtherapee.com), which is based on gtkmm 3. One user has recently reported very slow startup times on Windows 10. After a series of emails, he has been able to reproduce the issue on a very small program that uses only gtkmm (that is, no rawtherapee involved at all).
According to the user, it takes about 7 seconds to show the window on his win10 machine, under normal circumstances. But occasionally this takes up to 40-50 seconds.
I have only a win7 VM (don't use windows normally) and could not reproduce the issue myself, but I still hope this could be of some use.
FYI, the original report and the follow-up conversation are online: https://discuss.pixls.us/t/rawtherapee-5-3-released
