Install Updates Graphical Glitch

[Mart]

Has anyone experienced an annoying graphical glitch when using Linux Lite's native update utility ('Install Updates')?

I've experienced this same glitch / bug in the past when running the 4 series and now it's happening again with LL 5.0. I've never experienced this issue with LL 3.8, which I'm still running as my main driver, and I've never had any other graphical problems or bugs with Linux Lite - it's that good. I'd like to move over to the 5 series permanently before the year is out, but would like to solve this issue before doing so.

To best explain this glitch / bug, I've posted the following images to illustrate the problem -



1. The updates are fetched and displayed as per normal.




2. 'Downloading - Please wait' - graphical horizontal moving bar window appears.




3. Glitch - graphical horizontal moving bar window blinks out and disappears as quickly as it first appears.




4. Empty screen follows - no graphical confirmation of progress and that updates are being installed and working.


When this first happened, I thought the updates had failed and tried to run the process again but was locked out and told that another process was working in the background.

What I discovered later was that the updates were still downloading and installing in the background, but I only realized this later when the 'Updates Successful' window finally popped-up.

I've tried to solve this bug by running Lite Tweaks 'Package System Repair' utility but this didn't help. I've also checked for broken dependencies in Synaptic but it tells me there are none.

Any suggestions about how to fix this small but annoying graphical glitch would be gratefully appreciated.

Thanks in advance for any help provided.
