Hi! User reported strange garbled UI on 2560x1920 (I think) screen: ah, 2560x1440 actually: https://i.imgur.com/0RgnITa.png I fired up Xephyr Xephyr :1 -screen 2560x1920 -dpi 200 DISPLAY=":1" starte16 and inside this started cin. Result was wrongly-positioned elements in project settings, for example. Of course it was fixable either by setting UI scale param to 1.0 or BC_SCALE variable Still, out-of-the-box experience was discouraging for user. I saw few interesting messages and captured them to log. bash-4.3# BC_SCALE=1.5 cin Cinelerra Infinity - built: Nov 1 2019 17:53:29 git://git.cinelerra-gg.org/goodguy/cinelerra.git (c) 2006-2019 Heroine Virtual Ltd. by Adam Williams (c) 2007-2019 cin5 derivative by W.P.
