When windows lose focus, they tend to forget what the screen resolution is: Windows shrink and any sub-windows' resolution gets reduced (size of fonts increase, image sizes increase, etc.). This happens in regular windowed mode as well as convergence. I've seen this in Linux as well as Windows 10 VMs, so it's likely not Tools-related. Unsure if it's part of this, but I've also noticed mouse clicks that occasionally don't register correctly. The whole release has a clunky feel about it in general. Was this tested before it was released? The release notes were sketchy, giving the usually lazy "stability and bug improvements". What stability problem could possibly be 'corrected' to introduce these new instabilities and bugs?
