What does this mean? QWindowsBackingStore::flush: GetDC failed()
-
Running on Windows 7, using Qt5.0.2
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.
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.
