Thank you for the link to this other thread.  I just tried soft proofing colours and it didn't make much of a difference to the document as it stands and I don't know enough about ICC options to know what would be the one I need. Perhaps a colour-blindness feature can be worked into Affinity in the future? Thanks for responding.

would be really nice to have this fixed

Still an issue as of 2 years later, but another workaround is to click the symbol, click the symbol tab, click the Sync button to unsync the symbol, and then you can hide it. But you won't be able to resync the hide/unhide after that.

This appears to still be an issue. When I hide an instance of a symbol, all instances are hidden.

Thanks - works fine but still it's a work around which should not be necessary.

Here is a list of known issues with third party software:
Capture One (Windows Explorer Integration)
Problem: Crash when attempting to open files (stack overflow in NVIDIA driver). Affects Capture One versions 20 and 21.
Cause: Capture One's Explorer integration crashes if more than one instance is running at once
Solution: Disable Windows Explorer Integration by renaming the C:\Program Files\Capture One\Capture One 20\WIC\WIC64 folder to something else. Note: If you have version 21, the directory will be C:\Program Files\Capture One\Capture One 21\WIC\WIC64. This assumes you haven't changed the default installation directory.

ASUS Sonic / ASUS GPU Tweak III / MSI Nahimic
Problem: User Interface elements can disappear or appear stretched
Cause: ASUS Sonic / ASUS GPU Tweak III / MSI Nahimic interferes with Direct3D9 renderering.
Detection: Check if Nahimic is running as an active Windows Service. Kill the service and see if the problem temporarily stops
Solution: Start the application with --no-hw-ui flag, or stop the software (this won't affect the driver or functionality of the sound card)

Brother Control Centre 4
Problem: Unable to update the Affinity applications (Setup Failed).
Cause: Brother Control Centre opens files within the existing Photo installation directly, preventing the old files from being removed (causing the setup to fail).
Solution: Close Brother Control Centre via the system tray, , or try restarting then immediately running the Affinity installer.

Fresco Logic Proxy Display Driver
Problem: Crashes at startup
Cause: It acts as a proxy display driver, but doesn't handle the kind of requests that WPF makes upon the Direct3D 11 runtime.
Solution: Uninstall, or try using --no-hw-ui and WARP renderer (unconfirmed fixes)

Problem: Crash when dragging in the Layers panel (reported with version 4.6.7.6 of My Endpoint Protector)
Cause: My Endpoint Protector injects itself into the application and attempts to handle messages on our behalf

NVIDIA Surround

Solution: Disable NVIDIA Surround. One user has suggested using FancyZones as Part of the Microsoft PowerToys project.

RivaTuner
Problem: Instant crash at application start
Cause: RivaTuner hooks into Direct3D libraries and injects its own code, which causes the crash (neither Serif or Microsoft are at fault)
Solution: 1.6.x.x attempts to catch the corruption, and offers a slower, software-only fallback (with a warning at startup). Alternatively you can tell RivaTuner to ignore the Affinity executables (also add help.exe and crashreport.exe) by adding them to the list and setting 'Application detection level' to 'None'.

This affects Designer, Photo and Publisher but I first found it in Designer so I decided to post it here.
Are you using the latest release version? - Yes; issue first noticed in 1.10.1, still exists with 1.10.3 Can you reproduce it? - Yes, always. Does it happen for a new document? - Yes, new/old documents and when no document open. If you cannot provide a sample document then please give an accurate description of the problem for example it should include most of the following:    What is your operating system and version (Windows 10, OSX Mojave, iOS 12 etc)? - Windows 10 Home v 21H1    Is hardware acceleration (in Preferences > Performance) ON or OFF ? (and have you tried the other setting?) - On, yes have tested Off, no difference    What happened for you (and what you expected to happen) - Hovering mouse pointer over menu items, studio tools, preference settings, other interface elements initially and intermittently causes them to disappear, reappear, or text to appear distorted within its original space.    Provide a recipe for creating the problem (step-by-step what you did). - e.g. open Designer, hover File menu ('File' disappears); or, open Preferences, access General, pass mouse pointer over items (see screenshot of typical results).    Screenshots (very handy) or a screen capture/video. - Attached.    Any unusual hardware (like tablets or external monitors or drives that may affect things) or relevant other applications like font managers or display managers. - Fontbase installed but whether running or not, issue occurs.    Did this same thing used to work and if so have you changed anything recently? (software or hardware) - Would be hard to precisely diagnose what/when system change (s/w install/uninstall, updates, etc.) might coincide with issue emerging, I don't use Affinity software daily and perhaps a week or more went by between me not experiencing this and then it starting to happen. If there is some cache or other common Affinity files I should delete, please advise. Or other promising troubleshooting steps to try. Thanks in advance!
