Hovering the mouse cursor inside a Content Browser folder that contains blueprints causes the memory usage to steadily increase. This only seems to occur with blueprint assets in the folder.
A user mentioned: "Well the main problem is that the Thumbnail previewer has been changed from 4.11 to 4.12. The thumbnail render now spawns via "SpawnPreviewActor" and then issues an Actor->Destroy() directly afterwards. It does this for every visible blueprint asset over and over depending on its update frequency."
The user reported experiencing a crash, but I have been unable to reproduce the crash on my end.
Found in 4.12 binary. Reproduced in Main CL 2994701.
This is a regression, could not reproduce in 4.11.2 binary.
1. Open the editor
2. Create a new First Person project
3. Go to Edit->Editor Preferences->Miscellaneous and enable the Show Frame Rate and Memory option
4. Open the Blueprints folder in the Content Browser
5. Hover your mouse over the Content Browser
Result: Watch the Objects and Memory steadily increase as long as you have your mouse inside the Content Browser.
