[Interest] QWindowsBackingStore::flush: GetDC failed()

[Jason Kretzer]

Just adding Additional information:
These messages are not coming from any code that I have written in the sense that I am actually directly calling the flush on the QWindowsBackingstore. It must be coming from a component(s) that I am using which are all standard Qt objects. I use QWebView, QMovie, QImage, QMediaPlayer. In my original post, I put that it was basically displaying images and perhaps I should have been more verbose. I also display html and small video snippets. I was mainly just curious if other folks had seen this and what their cause had been.

Good Morning,

Had an app that I am working on suddenly stop after a couple of days on continuous use - basically just rotating a series of images on the screen.  The log filled with these entries.  They were intermittent at first but then eventually took over the log with these, over and over again.

CRITICAL: QWindowsBackingStore::flush: GetDC failed ()
CRITICAL: QWindowsBackingStore::flush: GetDC failed ()
CRITICAL: QWindowsBackingStore::flush: GetDC failed ()
CRITICAL: QWindowsBackingStore::flush: GetDC failed ()
CRITICAL: QWindowsBackingStore::flush: GetDC failed ()

Any ideas on how to keep this from happening or even what these mean?  I googled this and I get a lot of BitBlt failed information, but none like these.

Thanks!

-Jason
