Symptom
After updating to Traktor Pro 3.9 (or higher) on Windows 10 and 11, Traktor display controllers such as the X1 MK3, S4MK3, D2, S5 or S8 show severe flickering on the displays. The computer screen's waveform display also stutters considerably.
This issue affects Windows machines with AMD graphics processors, such as the AMD Radeon Pro series, and occurred after upgrading Traktor to a new version of the Qt graphics framework (5 to 6) used to render the display.
Updating the AMD drivers unfortunately does not fix this problem, nor does changing the driver settings.
Cause
The removal of an OpenGL compatibility library in Qt6 has revealed a previously hidden problem with Traktor's OpenGL implementation and Windows AMD drivers causing them not to load. The result is a fallback to the much slower software rendering, which causes the flickering.
Solution
The problem has been solved in version 3.10.1. Please update Traktor Pro to the latest version in Native Access.
