S2719DGF, G-Sync error message when you use ALT-TAB

Hello. So as most of you probably already know NVIDIA gave us an option to use G-SYNC (if you are using NVIDIA GPU instead of AMD GPU) on most AdaptiveSync (Freesync) monitors. Not all of them have a certificate but the feature works on almost every one of them. The same goes for DELL S2719DGF. G-Sync works as intended on 2560x1440 on 155 hz (from the range from 40 to 155 hz if the monitor is overclocked using a DisplayPort cable). I have realized that there are some minor issues. If you use Alt-tab to change windows sometimes you get an error message saying the following (check the link with the photo). It does not happen every time you alt-tab, more like it happens every third or fourth time or so. And the only time you get this errror message is if you alt-tab. If you alt-tab again the problem dissapears but it appears again after a few alt-tabs. So I was wondering if there is any way to patch this up from your side? I would really appreciate if this were possible since the monitor is great and the G-Sync feels amazing! Thank you!
