#1681 SciTE window refresh problem

[John]

SciTE has been my favorite editor for many years, but a recent system upgrade (Linux Mint 17.1, 64-bit, SciTE version 3.3.5) has introduced a new problem. Scrolling text up or down, especially at high speed, causes the window to flash black for a few milliseconds while updating.

I ran SciTE in a terminal session, opened a long text file, and scrolled it up and down. The following message was generated several times:

*** BUG ***
In pixman_region32_init_rect: Invalid rectangle passed
Set a breakpoint on '_pixman_log_error' to debug

This seems to be consistant and repeatable. Any suggestion on how to diagnose or correct this would be appreciated. System has libpixman-1-0 (0.30.2-2ubuntu1) installed.

3.3.5 is 15 months old and there have been changes to GTK+ platform layer code since then, notably [bugs:#1567]. First thing to do is update to current release 3.5.2 and see if that fixes the problem.

Another thing to do is to compile for debug "make DEBUG=1", run inside a debugger (I like the GUI debugger in Qt Creator), set a breakpoint on '_pixman_log_error' like the message says and look at the stack trace at that point to see which call Scintilla is making at that point.

Thanks. It seems that the latest version of SciTE is not available in the current Mint/Ubuntu repositories, but I'll keep checking for updates.
