UNSOLVED
P3421W, DDM, CTRL + SHIFT remains virtually pressed
Hello,
When switching sources with CTRL + SHIFT + Z hotkeys, the CTRL + SHIFT remains virtually pressed. This can be observed with Microsoft On-Screen Keyboard. The importance of keys assigned is not important as it happens with other key combinations as well.
This issue was present in DDM 1.0, fixed with the release of the new DDM 2.0.0.135, then issue reintroduced with version DDM 2.1.0.45.
P3421W firmware version M2B207.
Steps to reproduce:
Make sure that DDM has the following configuration as depicted in the pictures below.
Press CTRL + SHIFT + Z between sources and notice that the keys remain pressed, to regain full keyboard functionality, CTRL + SHIFT needs to be pressed again.
Specs:
Please fix this behavior. Note that this is not a hardware fault or keyboard fault, it is a software fault. This was tested with three different types of USB keyboards.
Thank you,
Eugen

As a baseline for troubleshooting, all PC's should be running the same version of DDM.

Indeed, well I can say that this issue disappeared entirely when both PCs have version 2.0.0.135.

* Clarify, when both PCs have DDM 2.1.0.45 installed, do you see the issue?

We do not have an ETA of a fix. Like you, we simply check the P3421W drivers page to see what versions are available. For now just use 2.0.0.135 on both PC.

After you press Z, the Ctrl and Shift keys must immediately be released. Are you perhaps lingering on the Ctrl and Shift keys?

Hi Chris,
I've reinstalled the old version 2.0.0.135 and it still occurs.
But there might be these factors that come into play:
1. CTRL + SHIFT is used by default for changing the language keyboard in Windows 10
2. If somehow the change occurs when the CTRL + SHIFT keys are still pressed. (transition to the other source can be fast or slow)
3. The other PC has the new version of DDU which force both ends to remain pressed.
