Colobot Demo installer window screenshot

With today's Git (wine-1.1.5-507-ge20ef50), in the process of testing bug
13932, I noticed that when the installer is at the file copy progress phase,
some elements of the window are not redrawn properly. A screenshot is attached.

I've noticed this bug in many programs.  Windows mandates to backpaging on,
while Linux and several other OS default to it off.

Thus, some programs assume that pages that never change will never be lost, and
thus will not redraw them when a redraw command is filed.

This is a simple architectural difference that could be patched in several
ways.

I think this should be filed under a wider bug if other people confirm my
results on more programs.

It's not clear what you mean by "backpaging", drawing "pages", and
"architectural difference". Painting in Wine is implemented internally,
and is triggered by repainting requests of applications and X expose events.

yeah, back-paging is an old X11 extension term, I probably shouldn't be using
it.  I should use a more descriptive.  In fact I shouldn't even look at this
from a X11 server-side perspective, even if that's where I think the problem
is.

The best way to describe this is that there is a difference in behavior between
X11 and Windows.  Windows MANDATES that video drivers store the content of
windows that are behind other windows remain in video memory, through a complex
method.

X11 implements this through an extension called "back paging" which it copies a
replica or "back page" of each window in an off screen buffer page, in the
video memory or memory allocated for quick transfer to the video card, in order
to restore if the program takes too long to do so itself, when called.  I
mentioned these memory pages above as pages.

Now an easy solution is best to render all wine windows using off screen
extensions than copy them to the screen.  This consumes a little more memory,
but actually saves processor time in redraws and properly replicates Win32
default behavior.

Sorry about taking the hardware-driver perspective without notice on a bug
report that was in software phrasing.

Wine never renders the windows, nor copies them from an off screen memory.
All Wine does is just generates the WM_PAINT messages which are either
handled by applications on their own or passed to default handlers.

Well yeah, come to think of it, where was my head the other day.  I could not
explain one thing in easy terms.

Of course, Wine doesn't do it that way, it currently relays through the
standard X11 methods, this is the problem.  X11 behaves differently than
windows.  We just need to find a way to get around this when programs don't
consider that undocumented Windows behavior may change.

I'd suggest to stop speculating, the problem needs to be investigated first.

Yes, we are saying the same thing and yet not understanding each other, it is
futile and I should search for the appropriate bug I was describing, and come
back with more solid info.  I do know what trace run to do, I just hope I can
find the bug I'm looking for.

The issue is still at 1.7.18

But I never see the background image you attached.

Not sure what it should look like when it's doing it right.

Also when you run the installer, it has weird characters I think that's another
bug.

After you press "Setup".

Also the game seem to have odd weird colorspace...

Hello Béla,

thanks for testing.

I'm resolving this as dupe of 35652 since I don't want my analysis there go to
waste (even if this report is older).

Thanks

Regards
