[wix-users] WiX bundle splash screen appears twice dependent on size and resolution

[Hoover, Jacob]

Hrm, maybe related to https://github.com/wixtoolset/wix3/blob/develop/src/burn/stub/stub.manifest and the fact that we don't declare the bundle as DPI aware. (I don't know that we are.)  In addition, we wouldn't know if a custom BA was DPI aware.

https://docs.microsoft.com/en-us/windows/win32/hidpi/setting-the-default-dpi-awareness-for-a-process

One could ponder setting a thread specific DPI aware near https://github.com/wixtoolset/wix3/blob/develop/src/burn/engine/splashscreen.cpp#L138 and test to see if that resolves the issue. (Only works in Windows 10+)

CustomBA.

Meanwhile we have found out that the size difference is not that important, but that we can see the same effect with all our (CustomBA) WiX bootstrapper splashes when we have set the Windows display settings to 125% scaling.

Using WixStdBA or a custom BA?

Any custom theming?

Hi there,

the splash screen of our current WiX bootstrapper project (using WiX 3.11.1) seems to appear twice at least on displays with 1600*1200 or higher resolution: After its first appearance, it vanishes and comes again at a slightly different position. This looks like some Windows component trying to resize something...

On displays with lower resolution, we cannot reproduce that behaviour yet.

In another bootstrapper project of ours, we do not see this effect. Having done a bit of investigation, we found out that the exact size of the bitmap may have an influence:
Bitmap size 600*300: no issue
Bitmap size 595*298: splash screen appears twice on high-resolution displays

Is this a known issue? Is there some workaround (apart from resizing the bitmap, which is tricky, as these bitmaps are made externally)?

Best regards

Matthias Reuss
