Menus don't fully appear

[Alan Pope 🍺🐧🐱 🦄]

Sometimes menus of applications or indicators don't fully appear. There's chunks missing. See attached picture. Sometimes I only see the drop shadow and not the full menu, sometimes part of the menu is drawn.

I also saw this one - but I noticed it while right-clicking on the window title-bar (as noted checkbox-unity tests results for windowmanagement). It happens seldomly, but still.

[Tim Penhey (thumper)]

I noticed this too once, but I've been unable to reproduce, and neither can Sam.

Can anyone give us any steps to reproduce?

[Sam Spilsbury (smspillaz)]

This patch backs out revision 2839 which *might* cause this. Please try it with this.

[Łukasz Zemczak (sil2100)]

I'll try this patch in a moment to check if it fixes this issue.

I am able to reproduce it quite easily through right-clicks on a window's title bar. How I reproduce it:
Move your mouse tho the title bar of any application, then perform a right-click quickly followed by a left-click. Usually on the second or third try, instead of the menu I only get the menu border and shadow, with the insides transparent.

This happens quite often on my laptop - like every 2-3 sequences as I mentioned above. In normal everyday usage it's a bit more rare, but still not uncommon - I would say every 10-15 times it happens by itself.

My laptop is Intel Core i7 Sandy Bridge based. It's an X220 which is pretty common in Canonical.

I find it happens randomly on various menus, both in the indicator area and application menus. More often happens on the first menu in the list i.e. the file menu rather than the help menu.

[Łukasz Zemczak (sil2100)]

I tried the back_out_2839.patch from Sam, but it doesn't seem to fix this problem (sadly). I can still reproduce it the same way as I mentioned before. But I can't seem to be able to reproduce it through normal application menus - i.e. on the File menu or indicators. I just notice it now in the right-click-on-window-title menu. I'll degrade back to the version before the patch to check if the thing I am describing isn't some other bug.

[Łukasz Zemczak (sil2100)]

Interesting.

From what I talked with Alan, it seems the bug I'm encountering and his bug are _probably_ different.

Alan said that he wasn't able to observe it on the title bar right-click menu - only on normal menus.
I, on the other hand, can only reproduce it on the title bar, but the bug never happens on normal menus. I'm using an ATI radeon mobility card with fglrx drivers on an old Intel Core2 Duo i386 laptop.

Further to Lukasz comment, I did just get it in a context menu of VirtualBox. I got the drop shadow only, then after a few seconds the window contents filled in.

[Łukasz Zemczak (sil2100)]

I'll try dealing with this one - if I won't be able to cope with it, I'll re-assign it back to Sam again ;)

[Alan Pope 🍺🐧🐱 🦄 (popey)]

I seem to be able to reproduce this, but it's difficult on a quick PC. It would probably be more apparent on something lower spec than an i7.

It seems to happen more if you're moving the mouse whilst clicking the menu area. So if you click a menu then move the mouse the next item it happens more often. Also if you move the mouse to a menu, click and then pull the mouse away before the menu has fully displayed then it often breaks up.

See the attached picture. I moved the mouse to the menu and then away and the menu looked unfinished.

[Łukasz Zemczak (sil2100)]

Thanks! I think I'm close to finding the issue here. It seems that menus (only the decorator menu and the application menus) have a wrongly set redraw region. The actual redraw region is off - sometimes it's off by a greater magnitude, and then the menu is invisible, or only by a small offset - and then the intersection is redrawn (and the menu is partially visible).

The funny part - the menu decorator (shadows, border) from compiz has the correct coordinates of the menu, but when the actual update of menu contents needs to happen - it's wrong.
Will find this ASAP.

[Łukasz Zemczak (sil2100)]

Still working on this one. It seems gtk_menu_popup in gwd sends invalid redraw events for the popup menu. Probably the reason might be some invalid x and y root coordinates. It's probably set not to 0,0 but to the cursor position/popup appearance position. I think it's like that because the update rectangle's x and y coords sent to compiz are 2*(x,y) of the popup position. Will finish this tomorrow!

[faiwer (faiwer)]

Daniel van Vugt (vanvugt), ok :) Example (attach photo) - in chromium web tool's. I have this bug everythere, but in Crhomium I can call it very easy (1-5 click's on "script" menu).

[faiwer (faiwer)]

A small addition: I'm currently using emerald, before - gtk-window-decorator. Bug was in the gtk-window-decorator, too.
