MainWindow flashes white prior to being rendered on start

Overview

When KeePassXC is launched, it displays a white background while the GUI is painted, resulting in an eye-straining white flash.

Steps to Reproduce

There are no particular steps involved besides launching the program.

Expected Behavior

There should be no flashes.

Actual Behavior

KeePassXC flashes a bright white, blank page.

Context

New installation at default settings.

KeePassXC - 2.7.5 and 2.8.0
Revision: 9d0537b and a5c1298

Operating System: Windows 10 22H2

I just tried 4 ways to prevent this and they all produced the same result. I believe this is a Qt problem at this time.

Interestingly, if I set Windows in High Contrast mode then the background "flash" is black/dark.

Closing the issue was an erroneous click on my part. Please ignore that.

In my experience, turning on Windows High Contrast mode seems to have made the flash more tolerable—quicker and a light-medium gray—but did not resolve it. This commit fixed the same problem in Shotcut:

Ah interesting hack, I didn't try messing with the opacity. I did try the delay timer though.
