Short description of error
This bug report very close to https://developer.blender.org/T67756 but with some additional. If you get the effect from T67756, and then click on UI elements blender freezes.
Exact steps for others to reproduce the error
- Create a shader and an image node.
- Click "Open Image". Go to a directory with many textures and go to "Thumbnail mode". It's easiest to reproduce if the thumbnails completely fill up the window. Open one of the images.
- Now click open again, and if the open button in the image node is at the same place as a thumbnail in the open dialog then it will start a drag-drop-action immediately.
- Click on resents directories. Or empty space. In 50% cases blender freezes.
