Ctrl-Shift keys and arrow keys

Greetings,

I have two separate issues with key combinations.

1) After upgrading to Fedora 31 and a somewhat recent version of ImageJ, I
startted noticing that the Ctrl-Shift keys commands stop working and the
letter key was being drawn in a tiny tab just outside the lower left
corner of the window. This randomly start happening, then after a while,
stop happening, I have yet to figure out the triggering event(s). Using
just the Ctrl OR shift modifier does not seem to be involved. Although I
do not suspect that this is a ImageJ issue per se, but this is the only
place that I have seen this.  Does anyone have any insight as to what this
is and how to disable it?

2) At some random point in ImageWindow(s) the up and down arrow keys will
perform the equivalent of the the + and - keys.  The left and right arrow
keys are not affected.  Causing a popup menu to appear seems to remap the
up and down arrow keys back to moving an Roi around.

Thanks in advance,

Fred
