Just to add some more info to this as it’s been an on/off issue for a couple of years now.1)
Driver version - 6.3.43-3 latest driver.
A clean install has been performed.
I did notice preferences remained despite deleting all files including hidden system files that have ‘Wacom’ in them, so any preferences/settings should have been removed. Is there another hidden file without ‘Wacom’ in it that may contain preferences? There was a detailed page here… https://www.wacom.com/en-au/support?gui ... -(manually
that explained the process, that no longer exists. I don’t know if it’s now different in Bug Sur?2)
Hardware - both Mac and Wacom device
iMac Pro (2017)
3.2 GHz 8-Core Intel Xeon W
32 GB 2666 MHz DDR4
OS: Big Sur 11.3.1
Apple Wireless keyboard connected via Bluetooth or USB-C
Intuos 5 Touch
Connected via USB directly to Mac
All express keys and touch ring are disabled.3)
What shortcut are you using
All keyboard modifier keys;
How that shortcut is assigned (what option in the driver settings) to the tablet, pen, or touch (what button on their specific model).
Not assigned to any shortcuts on Wacom device. Just standard Mac keyboard modifier keys.5)
How the shortcut is used in a specific application.
Any shortcut command that utilises the command/option/shift/control keys. Doesn’t seem to be application-specific, will do it any application and Finder. It seems to be random, but quite often.6)
Expected result vs observed result
Key behaves as though it is pressed when it is not when clicking with the Wacom Pen. A single press of the key again will behave as though it has been released. The next use of the key is likely to behave normally and as expected.
The key can also behave like it hasn’t been pressed when it has.
Extremely frustrating in Photoshop/Illustrator/InDesign where the modifier keys change the function of the tool you are using.
Some non-Photoshop/Illustrator examples;
Ctrl-Click Outlook definitely caused the Ctrl-key to behave as though it was still pressed. Single-click with Wacom pen was behaving like a right mouse click (as it should fi the key was pressed). Pressing the Ctrl-key again releases it.
Was in Chrome, Option-clicked on the desktop to hide chrome, so now in Finder, then just clicked on outlook icon in the dock, Finder gets hidden, clicked on Teams, Outlook gets hidden. Next keypress was Command, now back to normal.
Just done it after waking the computer to the login screen. Hit the space bar to wake the computer up. Typed in the password and hit enter. Click on teams in the dock and it behaves as if the command key was pressed and opens the application finder window and highlights teams. I didn’t even use the command key this time.
6.3.41-2 did not have this problem and was what I was running until early May in Catalina. I was forced into updating to Big Sur where it didn’t behave properly with Apple's security settings so had to update the Wacom driver. All driver versions since 6.3.41-2 have had sticky key issues for me. All on the same Mac listed above.
Was also present on a Mac 'Bin' last year where I had to roll back to a previous version, that was an earlier version than 6.3.41-2 but can’t remember which version.
