Alexandre Julliard has changed a strangeness of BeginPaint : when the update region is null, Wine used to paint the whole window. New code set an empty painting rectangle. However, if the empty update region comes from an earlier Wine bug, the new code replaces excessive repainting with no repainting at all. I have already an app that shows this problem. As I was saying in reply to Andi Mohr, better code can reveal better old bugs... Gerard

Improved redraw performance when application loaded
by Dave Hawkes 13 Dec '01

13 Dec '01

changelog: Reduced the time for a window with many child windows to be displayed. More info: A large application was taking up to 10 seconds to display its main window. This appears to be due to X individually exposing every child window (of which there are very many) of the main application window and then wine forcing a redraw on the parent of every child and then all the subchildren again (!) resulting in the accumulation of a huge redraw list. This patch will force a redraw only on the child and not the parent as X will eventually expose that anyway. After applying this patch the initial redraw dropped from around 10 seconds to about 2 seconds and I could not find any painting problems If anyone else is having slow application loading problems of this nature, then please try this patch.

This does not mean that the patch is wrong of course - maybe 2 bugs were compensating each other before. Gerard

This patch causes both Riven and Myst to immediately freeze for me, and no sound at all. Without the patch, the sound in Myst works pretty good (occasional brief dropouts). In Riven without the patch, only the opening sequence has sound, and that has many large dropouts. I'm using ALSA drivers in Redhat. Duane

Uncleared WM_PAINT loop problem
by Dave Hawkes 12 Dec '01

12 Dec '01

Hi, I have a problem where an edit control get stuck in an infinite WM_PAINT loop. BeginPaint never clears the paint count because of this code: if(((hrgnUpdate = wndPtr->hrgnUpdate) != 0) || (wndPtr->flags & WIN_INTERNAL_PAINT)) add_paint_count( hwnd, -1 ); if wndPtr->hrgnUpdate is 0 then the paint count is never decremented here and nowhere else attempts to decrement it and we land up in an infinite paint loop. I'm not sure how we get to this point the a NULL update region (which may be a bug anyway), but there should still be a method of breaking out of this loop once we are there. I tried removing the test and always calling add_paint_count and this appears to fix the problem. Before I submit this change, does anyone know the original reason for this test in the first place? Thanks Dave Hawkes
