The good news is that this bug was fixed on Tribble on March 15, 2017. The bad news is that the March 15th Tribble patch also contained a number of unannounced graphics changes. Since you don't run Lighting 2.0, these changes will probably affect you as well. For more information, see the link below.
The graphics when Lighting 2.0 is turned off was "updated" a few weeks ago. Activating Lighting 2.0 should fix the issue, but it a bit demanding so if you have integrated graphics or a weak dedicated GPU, then you will definitely notice a decrease in performance when it is activated.
