Dear Seamly2D developers, first of all thank you for making this great tool! I experience the issue above and maybe you can reproduce and fit it. I use an older intel based macbook pro 15 with Big Sur 11.7.6. My desktop is set to dark color scheme and the resolution of the retina is set to the max. Please let me know if you need further information. Thank you in advance!
