This issue comes only into effect in case the hardware acceleration is active. That is the reason why older versions of TX Text Control are not affected. Since version 24.0 (X14), TX Text Control uses the WriteableBitmap to render text onto a DrawingContext.

On Iris Xe Graphics, UI elements don't refresh after they are initially rendered on applications that leverage Windows Presentation Foundation (WPF) when hardware acceleration is active. This problem affects many vendors and libraries that use the WriteableBitmap class including SkiaSharp, CefSharp and apparently TX Text Control. Many Dell machines come with these processors by default, but it is not limited to this one vendor. WPF - cannot redraw page on Intel 11th Core Iris Xe Integration graphic card #3817 What is Affected?Īll Intel® Iris® Xe Graphics adapters part of the 11th generation Intel® processors are affected. This problem is discussed in the WPF GitHub repository: After version 24.0, we switched the rendering to the affected WriteableBitmap. This problem exists in all versions of TX Text Control. Common reports confirm that the document is not rendered properly and the content is not visible before it is changed or the document is zoomed.

Text Control users reported issues on machines with specific Intel graphics adapters.
