Out of graphic memory - application crash after days

The attachment link seems to be invalid.

From the sound of it you are leaking memory, like having unmatched new/delete, or you are keeping memory around that you actually don't need anymore.

yeah, sounds like that to me too. However, I cannot find, where the issue comes from. Do you have any suggestions?

[anda_skoa]

Check if all new are paired with delete, check if you store things in a map or hash and maybe never remove anything.

You can also disable certain code, e.g.not do anything for updates and see if that does not increase memory.
Then the leak must be in the update handling and so forth.

Ideally of course you'd use a leak checker, not sure if Windows has something like Vagrind for Unix systems.

Maybe the clang address sanitizer if you can build with clang.

Hi, I often used Visual Leak Detector together with Visual Studio.

Oh, just saw that the code is not readable. Let me link the file once more: QPainter_Issue.cpp

Thx.

My guess would be QImageController::_images growing endlessly.
