MyGUI is crashing on a second monitor #238

Open corentinjaffre opened 2 years ago

corentinjaffre commented 2 years ago

Tried the demos (ex: Demo_PanelView.exe), with Ogre 1.13.2, using directX9 and they crash when I move the window on my second screen.

Could be an issue with the font textures: From Paroj: My guess would be that the MyGUI Fonts are manually created but without providing a loader callback, so we cannot auto-restore them.

My guess would be that the MyGUI Fonts are manually created but without providing a loader callback, so we cannot auto-restore them.

MyGUI always handled that. Also not auto-restoring resources would cause empty data rather than crash in most cases. Could you be more specific about the crash? Logs, crash callstack, error message, etc.

When I move Demo_PanelView.exe to the 2nd monitor: "cannot increment value-initialized map/set iterator" in D3D9ResourceManager::notifyOnDeviceCreate(IDirect3DDevice9* d3d9Device) Seems to be with Ogre::Resource = {mCreator=0x0000000000443f70 {...} mName="97634480_TrueTypeFont" mGroup="MyGuiResourceGroup" ...}

Ogre.log doesn't have the time to update its log before the crash, so there is no relevant information in it.

My call stack:

looks like your loader becomes invalid, while the texture is still alive: https://forums.ogre3d.org/viewtopic.php?p=552832#p552832
