Invalid hotSpot

[fnJeff]

Describe the bug
The viewer creates a popup window titled "TigerVNC Viewer : Error" and the error message "Invalid hotSpot" after connecting succesfully and typing a single character into a shell or text editor. I was able to use Ctrl-Tab and Shift-Ctrl-Tab to switch between desktops normally. But as soon as I click into an editor or a shell and type a character, it crashses with the error message. After reconnecting, I see that the character I typed was there in the shell/editor. Hitting the backspace key to erase this character did not cause the error/crash.

To Reproduce

1. Connect to server using java client 1.14.1
2. Click into a shell or text editor
3. Type alphanumeric character (backspace did not cause the error)

Expected behavior
No crash

Not sure if it helps or not, but I've been using java version 1.13.0 and earlier and have never seen this issue before. I saw the same problem in 1.14.0.
Since it seems related to scaling, monitor's actual resolution is normal 4K, while you can see the actual resolution in the connection screenshot. I added a screenshot to the original post of my exact configuration from the Screen tab in case it helps narrow it down.

Any luck reproducing this? Any idea on an ETA for a fix candidate?

The main reason I'm pushing a little is because IT is saying that slowness issues people are experiencing (after upgrading our VDIs to Rocky 8 on ESXi) can be addressed by using 1.14.x version of the viewer, which I can't do because of this issue. I'm stuck at 1.13.0 and with the slowness.

Sorry but I haven’t had a chance to look at it yet but I’m planning to do this week. Sent from Gmail Mobile

Perfect, thanks for the update. Looking forward to your findings and hopefully an easy fix.
