I have been using Krita for about 3 weeks now and I have a bug when in 'wrap around mode'. If I change a layers opacity or visibility it doesn't update until I mouse over the canvas. However it happens about 90% of the time. The other 10% of the time it does update.

Windows 10 Home

Please let me know if there is any additional information on the pc that would help diagnose the cause.
Thanks.

With version 4.4.2 installed on Windows 10 Pro, I don't see this happening at all after many operations.
Wrap Around mode needs canvas graphics acceleration enabled so you could try changing the Preferred Renderer from Angle to OpenGL or vice versa, at:
Settings -> Configure Krita -> Display group -> Canvas Acceleration tab (restart is needed).

If that doesn't work then you could try updating your video drivers.
I can't think of any Windows settings that could influence this but I'm not very familiar with Windows.
