Affinity Photo crashing when changing opacity

[CM Lowry]

1. What Application are you using?  Photo
2. Are you using the latest release version? Yes 2.6.0
3. Can you reproduce it? Yes.
4. Does it happen for a new document? If not can you upload a document that shows the problem? Yes I can recreate it
5. What is your operating system and version (Windows 11, OSX Ventura, iOS 16 etc)? Windows 10
6.  Is hardware acceleration (in Preferences > Performance) ON or OFF ?  ON. Doesn't happen when off (I think)
7. Provide a recipe for creating the problem (step-by-step what you did): Below

Create a new document. Create 3 Rectangles of colour and set them to multiply. Drop in a decent sized image file (5+Mb), don't rasterise it, and mess around with the opacity sliding scale on the image. Slide will freeze and Photo will crash.

Happens all the time in files when I'm adjusting opacity in Photo. I can do exactly the same stuff in Photo persona of Publisher and it doesn't crash.

Also happens when doing Ctrl+Scrollwheel zooms

 

1.    Screenshots (very handy) or a screen capture/video. Screenshot and video attached
2.    Any unusual hardware (like tablets or external monitors or drives that may affect things) or relevant other applications like font managers or display managers. I use two monitors, but happens without them.
3.    Did this same thing used to work and if so have you changed anything recently? Been happening for ages, I'm lazy reporting it. no changes.

Hi @CM Lowry,

Not an issue I've been able to replicate so far, if you're also experiencing intermittent crashes when panning around and zooming on the canvas this can be indicative of an issue specific to your local environment/device.

I'd first suggest disabling Hardware Acceleration and attempt to confirm that this is the cause. I'd also recommend updating your Graphics Drivers by following the guidance in the FAQ linked below. If given the option, select custom installation and perform a clean installation of your drivers.
