When another user shares their desktop I have found a problem when I use 100% scale and their desktop is smaller than my window. GotoMeeting tries to center their desktop in my window. Sometimes I notice their text is blurry when my local GotoMeeting window is maximized to my desktop. If I drag the corner of my window by exactly 1 pixel up and 1 pixel left or right, I can get the remote screen to render correctly. It appears that GotoMeeting's scaling engine will take a perfect pixel-for-pixel image and offset it by one half pixel. Then render everything blurry. I think this should be an easy thing to fix. Below you will see 2 screenshots I took of GotoMeeting rendering the remote screen share. The first image is the original and blurry. The second image show how clear it gets when I simply move the corner of my window by 1 pixel in the X and Y directions.
I'm running GotoMeeting 10.16.0 on a Windows 10 PC. This problem has been seen for many months, so it predates the current software version.
I'm using a 1920x1080 monitor with the GotoMeeting windows maximized (the Windows task bar still shows at the bottom). The screen being shared is probably from a laptop at 1366x768. I can check on that to be sure.
