There's a issue with the download bar gets height reduced and also partially under the Windows task bar (instead of place it upon). I notice that going to Appearace/Style and clicking on [Reset Custom] it fix the issue, but of course you lost all style configurations. Restoring a previous backup works as for colors etc. but it broke again the download bar height and placement.
For the moment the only way to get rid is make a Reset and re-assigns settings manually. For some time it works, but then it breaks again.
