Dear Maintainer,

While working in Terminal Emulator, I moved the mouse pointer out of
the window.  A spurious window resize event occurred, leaving a size
indicator "80x32" on the screen.  I minimized the window and the
indicator remained on the desktop.  I restored the Terminal window and
the indicator remained.  I switched to another Workspace, which seemed
correct, switched back, and the indicator was still there.  I tried
typing in the Terminal windows and the keyboard did not work.  I was
able to select other Terminal windows.  The keyboard still did not
work.  I closed the various open windows by clicking the Close
decoration.  I right-clicked on the minimized windows in Window
Buttons, but their context menus did not open.  I clicked on the
minimized windows in Windows Button and they restored.  I closed them
via the Close decoration.  I clicked the Application Menu and its menu
did not open.  I pressed Ctrl+Alt+Del and the screen went black.  After
5~10 seconds, the graphical login screen appeared.  I logged in,
opened a terminal, and filed this bug report.


This machine is a Dell Latitude E6520 with an Intel Core i7-2720QM
processor, 16GB memory, 60 GB SSD, and Intel/NVIDIA Optimus graphics.


When I installed Debian 10.8 on it 7+ months ago, YouTube videos
crashed after ~20 minutes.  I pulled the system disk and put it on
the shelf.  Every few weeks I would install the disk, update/ upgrade,
and test again.


I tried installing the NVIDIA proprietary driver.  That was a disaster.
I blame PEBKAC.


After upgrading to 10.9, YouTube videos crashed after a few hours.


After upgrading to 10.0, YouTube videos stopped crashing.  I then
started using the machine as a daily driver.  Unfortunately, I have
been experiencing desktop malfunctions ever since.  Their frequency has
increased recently (I just experienced a spurious desktop select (?)
event when moving the mouse cursor out of a Terminal window).  I can
usually get out of them by operating various windows, decorations,
buttons, menus, etc., but not always.


I have tested Debian 10 OS disk in a desktop machine with an Intel
DQ67SW motherbaord, Intel Core i7-2600S processor, and 8 GB memory.
That machine has Intel integrated graphics and has been reliable since
Debian 6 or 7 (~2013?).


Therefore, I suspect the problem is related to the Optimus graphics
and/or nouveau driver.

I moved the Debian 10 instance disk from the Dell Latitude E6520 laptop
with Optimus graphics to a Intel DQ67SW motherboard desktop with Intel
integrated graphics.  The Xfce desktop issues remain.


I installed a Debian 9 instance disk into the DQ67SW and ran it for
several hours.  I did not experience any Xfce desktop issues.


I moved the Debian 9 instance disk to the E6520 and ran it for several
hours.  I experienced one event where a second instance of Oracle VM
VirtualBox Manager version 6.1.26 r145957 (Qt5.7.1) spontaneously opened
and then minimized.

I moved the Debian 10 disk into the Dell Latitude E6520 laptop with
optimus graphics.  I logged in and opened my usual set of applications
-- Thunderbird, Firefox, 2 Thunderbird, and 6 Terminal.  I started the 
Oracle VM VirtualBox Manager and started a VM in headless mode and then
closed the Manager.  I used the machine for several hours without any
problems.  When I moved the mouse pointer from a Terminal window into
the Xfce panel, the GUI freaked out, several things flashed on and off
the desktop, and I ended up with a dialog asking me to confirm deletion
of Workspace 2.

Firefox has been causing the most problems recently.  I was just
browsing eBay and looking at photographs.  Firefox crashed, crashed
Thunderbird, a pop-up menu appeared on the desktop, and the Xfce panel
moved away whenever the mouse pointer got near it.

I have been testing video playback and browser graphics/ javascript (?)
issues on Debian 9, 10, and 11 with Xfce on two computers:

1.  Dell Latitude E6520 with Intel i7-2720QM processor (Intel HD
Graphics 3000) and NVIDIA NVS 4200M (NVIDIA Optimus).

2.  Tower desktop with Intel DQ67SW motherboard and Intel i7-2600S
processor (Intel HD Graphics 2000).


Amazon Prime video, YouTube video, and eBay image browsing seems to work
okay on the Intel DQ67SW for Debian 9, 10, and 11.

crashes/ freaks out within minutes on Debian 10.

I found my spare mouse and plugged it in last week.  The random GUI
event storms have disappeared.  The old mouse is now on the recycle pile.


Please close the bug report.


Sorry for the confusion,

David
