I updated all the Windows apps to 1.9 (exactly 1.9.0.932). I had no problems with a couple of projects. However, now, when Photo starts up, the interface looks normal. I create a new document, or load as saved one, the canvas loads, displaying blank, if new, or the artwork if loading an existing one. At this point, the interface freezes. The CPU goes higher for the app (< 50%), and it becomes unresponsive. I have to kill the app.
At the start, the menus work; at the Preferences section, I reset all tools to their factory defaults and disabled the hardware acceleration. No success, same behaviour.
I also tried Beta 1.9.1.963 unsuccessfully. When loading an existing document, the canvas is never loads, and a message remains at the top-right corner of the main window saying "Loading 1 document..." and it's stuck for good. I cannot close the window as it pops up a message to wait because a document is loading. I have to kill the program.
I'm running a Lenovo X1 G3 [all updates applied] on Windows 10 Pro (Build 19042.804)
I'll wait for an update before I downgrade to the previous version.
