@remmas00 Since you didn't elaborate much, and although most of the users are focusing on the torrent client's UI, I like to tackle it from another angle. Looks like you're using the Windows 7 Basic theme without Aero. While it could be just by choice, there's a possibility that you have not installed the proper graphics driver for your GPU yet, hence the absurd brightness might has its root in the generic rendering driver. This is especially true for laptop displays. Nonetheless, we don't need to throw rocks in the dark, so kindly add some more information about your issue.
The other softwares look fine, when it comes to the font at least, look here is superium. Now, compare it with transmission or qbittorrent font. It is the font that is bugging me a lot.
I have posready embedded, and here is the list of drivers. It looked installed, but i used snappy driver installer, the one on source fourge.
