Created attachment 542982 [details] Screenshot of OpenToonz Colours of timeline are broken so I can not see separate frames. I didn't have this problem in media-gfx/opentoonz-1.1.2. In case it's important, I use x11-wm/awesome-4.2-r2.
Thank you for the report. Please recompile and *attach* the logfiles and paste the emerge info as described on https://wiki.gentoo.org/wiki/Attach_the_logs_to_the_bug_ticket The logs must be part of the ticket, but not on external websites. Please reopen this ticket (Status:unconfirmed) afterwards. Does it work again, if you downgrade?
I've found instructions in build.log: * It is supposedly optional but some files are * actually required to run the executable properly. * * The .config/OpenToonz/ directory in your home folder * will contain your settings, work and other files. * * We need to create it from the command-line: * * $ mkdir -p $HOME/.config/OpenToonz * $ cp -r /usr/share/opentoonz/stuff/ $HOME/.config/OpenToonz/ Problem was resolved after I've done that.
