Install Updates Graphical Glitch

[Şerban S.]

The silent updating problem has been reported at least twice on the forum before.  It seems to be a edge case but is not limited to one user.

There was some progress/diagnosis on Derek_'s thread after DeepThought found and reported a divide by zero error when running lite-updates from the terminal which seemed to provide some insight.

Code:

Reviewing this thread might be relevant in this case.

Thanks for the tip! (I did it on the forum interface too! )
Well, I have a good practice when it comes to "blind running-something".
I make heavy use of Task Manager. Since it is in my StartUp, I look at the threads that are running, each time I find something looking weird.
If the updater is running without refreshing its GUI, that is clearly a video issue, so checking if there is a PID running, will make it clear if the Updater is running so, I can make a sound decision on what to do, if this is the case.
This can be applied on any App that went sideways, more often for video glitches reasons.
Sometimes, it happens. Maybe because two apps with different VCLs (Visual Class Libraries, such as Qt and GTK) are running simultaneously and actually, they are doing something. I use DoubleCommander for one, an this is Qt based, while the rest of the environnement is GTK based. So, sometimes if a third app starts, might get some trouble that is likely to appear randomly enough and rarely enough to be able to track it down.
One known issue, is Thunar FM, that caused lots of trouble with the panels, leading to desktop Panel 1 freeze, leaving out the only option to handle from keyboard accelerators, everything on the desktop. Happily for me, I'm using computers for over 25 years and I remember some keys by hard so when it happens, I usually get along without "external" assistance.
It is difficult to talk about this kind of issue that in fact consists in mixing DEs and video compatibilities among concurrent VCLs running simultaneously. Many users barely care for what is "under the hood" and expect the Windows "Point'n'click" philosophy work "out-of-the-box" on Linux, all the time...

Have a great day!
