V2.6 bugs on open and handling files

[resunoiz]

• Every time I start Photo or Designer when I click to open a new file, the program shuts down, no crashes simply shuts down. At second opening, works normally.
• If I open more than 4-5 files, the program becomes sludgy and closes, or (worst) becomes very, very, very slow. Like you need 20-30 seconds to click on a part to clone (alt+click) and then start painting with clone. 
• Impossible to work with big files (5000px width, Canon fotocamera): only little files or the program is useless
• In Affinity designer "export" preview is low res, non resizable, almost useless.

This last update makes the program behaviour like a cheap free trial one, by far not comparable to photoshop workflow.

Have you tried disabling Settings > Performance > Hardware acceleration? It would be useful for Serif to see a screenshot of your Performance settings and to know exactly which version and update of Windows you're using.

Good luck
