Rendering error on multiple monitors

[Jorge Castro]

Sometimes the grippie thing shows up on the wrong monitor. (See red highlights in the screenshot)

[Andrea Cimitan (cimi)]

That's a feature! So that you are sure to use both monitors :D ahaha

(I'm kidding)

Well, will figure out... looks like I'm not getting the screen size of the right monitor

[Andrea Cimitan (cimi)]

the bug is in os_scrollbar_sanitize_x and os_scrollbar_sanitize_y.
We should use gdk_screen_get_monitor_geometry instead gdk_screen_get_width... (or a combo), if someone is willing to do these calculations, it is pure math (bitesize bug?)

[Diska (discardi-nicola)]

with nautilus and gedit scrollbar work fine for me. can you try if it work bad only with that specific program? and tell me what program you was using?

[Andrea Cimitan (cimi)]

Diska it's clearly a bug in the positioning, I'm not taking into account the phisical monitors, the thumb should be constrained to the phisical screen where the scrollbar is

[Diska (discardi-nicola)]

i understand. i was trying to reproduce case but with application above all work fine.

[Bilal Akhtar (bilalakhtar)]

I'll try fixing this.

[Andrea Cimitan (cimi)]

awesome

Hi Andrea,

I've tested my branch on a dual monitor setup. In the test I opened a window of gedit and I checked whether the scrollbars worked well on both the monitors. I tested corner cases as well. However there was 1 small flaw detected in the test: In the first monitor the grippie came on the right side when not maximized and left side when maximized. But on the second monitor the grippie came on the left side always, regardless of the fact whether the window was maximised or not. A very small flaw, but the rest was flawless.

I am proposing this branch to be merged into trunk

[Bilal Akhtar (bilalakhtar)]

Weird. I downgraded to the PPA version, and the bug didn't exist there! It was a completely flawless experience there, and even the left-side grippie problem (which is evident in my branch) didn't occur there.

Jorge, Can you confirm whether this is fixed for you? If it is, then this bug is closed without any branch merge, etc.

[Andrea Cimitan (cimi)]

it can't be fixed, because my code is clearly bugged :D
I will fix id someday, if you are not going to fix this

[Bilal Akhtar (bilalakhtar)]

After discussion with Cimi on IRC, I decided to leave this bug as my way of fixing it failed partially. Anyone wanting to fix this bug can look at the linked branch which contains the code I wrote for fixing this bug.
