The behavior is observed when running brave-browser on TCL12 x86_64 or TCL11.1 x86_64 with Xorg (Xvesa doesn't work with my hardware, so I can't test it). Other tested browsers (e.g., firefox, chromium) do not have this problem. The same exact brave-browser binary running on a different OS (e.g., Devuan) on this same machine does not have this problem.
A quick and easy way to reproduce:
1. Load brave-browser.tcz
2. Start the browser and go to http://forum.tinycorelinux.net
3. Login to the forum
4. Hover over "My Messages" to activate the popup menu
5. Click on "Read your messages"
6. The menu disappears without taking you to messages section :-\
I've noticed the problem on multiple websites, so it is not a problem with the TCL forum site.
All the relevant software (Xorg, gtk3, the browser itself) is so complex that I'm at a loss how to even start troubleshooting this. Any ideas?
-
Hi GNUser
I would suggest the first thing to try is start the browser from a terminal and see if any errors/warnings pop up.
-
Hi, Rich. Good idea. Here you go:
$ brave-browser

These errors scroll by when first launching brave-browser. Once browser is running, no additional errors show up in the terminal. Also, no errors show up in the terminal when popup menus disappear.
BTW, launching chromium from the terminal shows the same errors and chromium doesn't have the problem I'm investigating, so I think the errors above are unrelated to my issue.

Quite a few apps seem to use dbus if the daemon is running and issue warning messages if it is not running.
I don't think running dbus will fix your problem, but you could give it a try.

...running brave-browser on TCL12 x86_64 or TCL11.1 x86_64 with Xorg (Xvesa doesn't work with my hardware, so I can't test it)
Xvesa is 32-bit only

Thanks, juanito. Having dbus running in the background does not help and, strangely, does not even cause the launch-time bus-related errors to go away:
$ s u d o /usr/local/etc/ini t.d/dbus start # spaces are to work around posting restrictions
$ pgrep -fa dbus
8886 /usr/local/bin/dbus-daemon --system
$ brave-browser

I did an internet search for flaky menu handling in chromium (browser on which brave is based) and some people solved it by going in browser's settings and unchecking "Use hardware acceleration when available". Alas, it made no difference for me.
[Rant follows: Kudos to the good folks creating a "small internet" (Gopher and Gemini) parallel to the WWW. When the WWW and browsers have become so complex that even just clicking on a menu is sometimes problematic, you know something is wrong. This issue is a good example of why the "small internet" folks are on to something. See https://en.wikipedia.org/wiki/Gemini_space (https://en.wikipedia.org/wiki/Gemini_space)]

The troublesome menus may be related to how brave-browser handles PHP. Here's the HTML code for the forum's "My Messages" menu, for example:
<li id="button_pm">
<a class="firstlevel" href="http://forum.tinycorelinux.net/index.php?action=pm">
<span class="firstlevel">My Messages</span>
</a>
<ul>
<li>
<a href="http://forum.tinycorelinux.net/index.php?action=pm">
<span>Read your messages</span>
</a>
</li>
<li>
<a href="http://forum.tinycorelinux.net/index.php?action=pm;sa=send">
<span class="last">Send a message</span>
</a>
</li>
</ul>
</li>

The fact that this problem does not affect the very same brave-browser binary running in a different GNU/Linux OS seems to suggest that it's not a PHP or CSS issue. Maybe the issue has something to do with how TCL's Xorg informs applications about left-clicks?
I have a workaround for now: Pressing the middle mouse button opens the desired menu item in a new tab. It's not ideal but it's better than nothing.
-
fluxbox is the culprit. When I tried running brave-browser in flwm the problem went away. Running brave-browser in Xorg without any window manager also works fine.
I've been using fluxbox too long to switch. I tried unchecking "Use system title bar and borders" in brave-browser but it doesn't help. fluxbox seems to somehow intercept and alter the left mouse click in a way that confuses brave-browser.
Is there a place other than ~/.fluxbox/keys where fluxbox looks for mouse button settings? Deleting ~/.fluxbox/keys and restarting fluxbox does not solve the problem.

Hi GNUser
... [8974:8974:0504/080909.931958:ERROR:browser_dm_token_storage_linux.cc(94)] Error: /etc/machine-id contains 0 characters (32 were expected).
This should fix that:
ln -s /var/lib/dbus/machine-id /etc/machine-id
You can read more about it and possible implications here:
https://forum.mxlinux.org/viewtopic.php?t=47482
[8974:9004:0504/080910.548014:ERROR:bus.cc(393)] Failed to connect to the bus: Could not parse server address: Unknown address type (examples of valid types are "tcp" and on UNIX "unix")
This didn't turn up anything, but I do have a thought on its possible cause. The ~/.xsession file typically includes:
-nolisten tcp
when it starts X (first line in file).
-
Thanks, Rich. Yes, the symlink made that particular error go away but makes no difference for my issue.
The issue seems to be that fluxbox affects the left mouse button in a way that brave-browser doesn't expect. I've filed a bug/support ticket with the fluxbox developers here:
https://sourceforge.net/p/fluxbox/bugs/1187/
In the meantime, if any fellow TCL+fluxbox users know how to tame fluxbox with regard to this issue, please do share.
-
Turns out this is one of those "second order" bugs that arise when a particular combination of applications is being used--in this case, fluxbox + certain versions of chromium (brave-browser is a chromium derivative):
https://bugs.chromium.org/p/chromium/issues/detail?id=713746
The workaround is to launch brave-browser with the "--disable-features=SendMouseLeaveEvents" flag:
$ brave-browser --disable-features=SendMouseLeaveEvents
Thread may be marked as solved :)

Hi GNUser
... certain versions of chromium (brave-browser is a chromium derivative): ...
What a coincidence. Searching on those dbus errors returned only chromium issues.
Fluxbox has 2 focus options, Click To Focus and Mouse Focus (focus follows mouse). Are you by any chance using
Mouse Focus? If you are, I bet changing to Click To Focus also fixes it.
-
I had tried all of fluxbox's focus options to no avail.
-
Hi GNUser
I saw a reference to sloppy focus (focus follows mouse) in the bug report you linked to causing the issue in a
different window manager (FVWM). Figured it might be an issue here too. Oh well.
