#585 Text display corruption on opening incsearch bar (CtrI-I)

Program (402)

System Details:
1) OS: FreeBSD 6.1 RELEASE
2) Compiler: gcc (i386-portbld-freebsd)
3) Motif: OpenMotif 2.2.3 (FreeBSD Port)
4) NEdit: v5.5 (FreeBSD Port)

Notes: NEdit, Motif built from source. Rest
binaries (stock).
Problem Description:
On pressing Ctrl-I to bring up the incremental-search bar, the text display becomes such that the topmost visible line of text is repeated for each line, with ugly artifacts in-between lines. A similar situation arises when scrolling upwards by arrow keys, or bringing up the status-line/incsearch bar/tabs via menu/keyboard actions. In short, any action which leads to text moving _1_line_down_ causes this problem. PageUp/PageDown or mouse-scrolling show no problems. When the display is corrupted, iconifying/deiconifying clears it up. However, NEdit is unusable as such.
Steps taken:
1) No app-defaults file. (Of course.)
2) *No* .Xdefaults/.Xresources file
3) No fancy window tools (xcompmgr and the like).
Just plain mwm.

The problem still occurs.

Other Motif Apps:
Run properly, including Xplore, xmmix, DDD, gVim.
None at present. I can attach screenshots.
Current Progress:
Trying to download and check with an NEdit binary.

    Nope. Using stock FreeBSD Xorg 6.9. BUT, I did have COMPOSITE enabled (via nVIDIA binary drivers), although not using xcompmgr (or any other compositing manager): only plain fvwm 2.4.19.



    Me: Disabling COMPOSITE extension cures this ill. So one may say that the ARGB
    visual is the cause of this. I am currently evaluating the fix mentioned by tringali.

    The problem exists since Xorg 6.8, but the Composite extension has probably been enabled by default only since 7.0.

    XLIB_SKIP_ARGB_VISUALS=1 will almost certainly work for you too.

    It does. Thanks everyone.
