MSAA warning comes up every time window is being resized

On displays that do not support MSAA, warning comes up every time window is being resized. The fix is to turn off MSAA but I would prefer if I could suppress the warning somehow.

Screenshot from rdp session into Lubuntu 18.04:

Yes, that’s it. The used MSAA being different from the one set might confuse people. While this could be fixed by remembering the last clamped MSAA value and only logging if it’s different I don’t think that this is worth the added complexity.
