I hope you've managed to fix this issue, but if you haven't the fix for this is very simple and it disappoints me that nobody from TeamViewer Support has bothered to rectify this in this post or for any of the other forum posts. Older versions of TeamViewer didn't have a hardware acceleration tick box in the settings, instead you had to enable/disable in Windows which is a bad idea, because doing so affects other applications on the computer. In recent years, applications TeamViewer included have been including a toggle box that allows you to enable/ disable it for that particular application. The Fix Anywho, to fix this problem open TeamViewer, go to Extras>>Options in the left pane select "Advanced">>Show Advanced Options, scroll down to the bottom of Advanced Options, below the "More" heading you will see a tickbox labelled "Disable Hardware Acceleration". If this option is unticked, tick it. If it's ticked, untick it.
