<![CDATA[Bug: Extremely poor performance/hitching until display settings are changed]]>Been having issues with poor performance when running f.lux, but it goes away when I change color settings in nVidia control panel. Doesn't seem to matter what settings i choose, RGB or YCbCr, full range or limited. Even selecting the option to let the OS control color doesn't help. Whenever I restart it has poor performance again until I change the settings.

Running Windows 10 x64 Build 17025.1000
Intel i5-7600k w/ 16GB RAM
Geforce GTX 960 /w driver 388.13
Dell ST2220L monitor

Love this program and haven't had any problems until now, but I can't run it with such low performance. Tried reinstalling F.lux, the video driver and the monitor driver to no avail.
