I use LinuxMint 17.3 Cinnamon in VirtualBox, 1920*1080 resolution is used in this machine, the Hi-DPI option is turned on. The host machine is Windows 10, with 3840*2160 resolution.
Despite turning on Hi-DPI option in LinuxMint, some applications become to look good for comfortable work, in terms of scaling, but python-tk GUI (python2) hasn't been changed - font size is tiny, changing of Font options in Cinnamon doesn't change fonts in tk. Is there any way to scale correctly already written tk GUI applications?
you can use the Clmage module to increase the resolution of your GUI render
