    Hi all,

    I have a running system based on Qt 5.4.2 + VS2013 on TabletPC using Windows 7 Embedded with GMA 600 GPU (with last drivers revision installed: 8.14.6.3077)
    I want to upgrade to Qt 5.11.2 + VS2015 to get access to QtQuickCompiler.

    I have installed Qt 5.11.2 on my device and rebuild application with new Qt version, but the application didn't work properly.
    Most of it works well, but some text is not correctly displayed:
    0_1541520134749_1b88bbb5-8a89-4a86-998c-a7f27000af12-image.png

    But when I use the raster driver (QT_OPENGL=software), it is display as expected:
    0_1541520232949_fbdb1d98-eee2-4811-9720-0f12cf92fb50-image.png

    All others texts are displayed as expected, just text on this extra layer is not correct.

    I have tried out many settings but nothing seems to have a positive effect:

    • QCoreApplication::setAttribute(Qt::AA_Use96Dpi);
    • QCoreApplication::setAttribute(Qt::AA_DisableHighDpiScaling);
    • QCoreApplication::setAttribute(Qt::AA_ForceRasterWidgets);
    • QCoreApplication::setAttribute(Qt::AA_ShareOpenGLContexts);

    Thanks for any help!

    Best regards

      I found a solution for my problem.
      I had to set renderType=Text.QtRendering to solve the issue.
      With Qt 5.4.2, I had to set renderType=Text.NativeRendering

      Very strange to me, but works ;)
