Drop-down position bug in Weston

I'm happy tu use Weston - a very simple desktop.
However many apps still use X, so I need Xwayland for compatibility.



Among the X apps, I have noticed an annoying bug. It goes like this:

bring up a dropdown menu. Move the window. Bring up the dropdown menu again, it has not moved with the window, it still appears at it's old location!

It will remain there - until I resize the window or until some internal event causes it's position to be recalculated.



It affects many apps (among them Chromium and Firefox). It also affects the contextual menu, drop-downs (autocomplete, etc.) and drag-and-drop areas. I have also observed it when using "sway" window manager instead of "weston".



Sublime Text and a bunch of other X apps seem to be immune. So I guess it is related to the toolkit or particular features that such apps use.



I have never observed this bug in any "native" Wayland apps.



Here is the thing:



I tried GNOME/Wayland and KDE/Wayland and didn't see that bug over there! Firefox, Chromium, it all works well over there!



At the moment I'm investigating, and have gathered some notes
(https://gist.github.com/rolfen/c57e4606856f900c654fabb5cf9a34b6)



I have built the latest version for Weston and Xwayland from source. Same.



I'm wondering if anyone knowledgeable in how these apps and window managers are assembled could help me draw some conclusions.

          How many registers does an x86_64 CPU actually have?

          Image
          Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
