I got this weird graphic bug (see image below) and it happens when i drag the cleint around or move my mouse over it. I was wondering if somebody knows what causes this. I just got my new pc today and i hope that its not something on my end but rather the client. When i click the client away and then go back to it or using the fullscreen button the weird graphic thing goes away.

This forum for the Galaxy Client Version 2, not Version 1. I suggest opening up a support ticket: https://support.gog.com/hc/en-us/categories/201553025-GOG-Galaxy

I have the same exact problem. It happens if I leave the mouse untouched but goes away as soon as I move mouse or click in window. It's weird but other than being really annoying doesn't seem to be causing any other problems. Watching this for answers.

I had the same problem start suddenly on 1.0 and now also its happening to me on 2.0 as well. Its worse when I have the window open over google chrome or any window like over Steam as well. I have tried different gpu drivers to no avail, this has been happening to me for a while now but I have not been able to find an answer as to why. I even tried gog support and they just told me to reinstall my graphics drivers, which I did using DDU on safe mode even.

It has to do with nvidia drivers, disable image sharpening and anisotropic filtering for galaxyclient.exe and galaxyclient helper.exe
