[jitsi-dev] New user UI bug report for devs


Dear Jitsi devs,

I have just downloaded and installed your "jitsi_2.8.5426-1_amd64.deb"
package on my Ubuntu 14.04 LTS laptop with build in webcam and noticed a
series of UI bugs. Running jitsi from the terminal for the first time, I
notice the following bugs:

Clicking on top bar: Tools > Options > Video > Encodings causes the
following error message to print to the terminal:

# A fatal error has been detected by the Java Runtime Environment:

hs_err_pid12715.log (143 KB)

hs_err_pid12876.log (143 KB)

hs_err_pid13114.log (142 KB)

The file hs_err_pid12715.log is attached. A similar crash occurs when I
click "Tools > Options > Video > More Settings"
The error message in the terminal is identical, but it produces a different
log file, /tmp/hs_err_pid12876.log, also attached

In case the WebCam has anything to do with it, I am using a System 76
Gallago Ultra Pro laptop with "BisonCam, NB Pro (/dev/video0)" Camera.

The "Tools > Options > Security" tab causes the exact same crash as well,
returning log file "hs_err_pid13114.log", attached.

If I close Jitsi via File > Exit and then enter "jitsi" into the terminal,
I get:
"Jitsi is already running and will handle your parameters (if any).
Launch with the --multiple param to override this behaviour."
^ Even though Jitsi is not running anymore. ^

Finally, under "Tools > Options > Advanced > Plug-ins", there is a vertical
scroll bar for scrolling up and down, but there is no horizontal scroll
bar. Some of the plugins, such as "Guava: Google Core Libraries to Java
15.0.0", have very long descriptions and the descriptions cannot fit on my
1920 by 1080 screen because there is no horizontal scroll bar. Adding a
horizontal scroll bar should be an easy fix.
