XPM images that are 1-pixel-high (or 1-pixel-wide) are not rendered correctly on nvidia hardware. x11-themes/icewm-themes-0.0.2 x11-wm/icewm-1.3.7-r1 x11-drivers/nvidia-drivers-319.60 x11-base/xorg-x11-7.4-r2 x11-base/xorg-server-1.14.3-r2 Hardware: on-board GeForce 8200 on ECS motherboard. I've had this same symptom in 2008 (5 years ago), in Frets on Fire game, with a different machine but also running nvidia-drivers. In-game textures that were less then 32 pixels were not rendered correctly. http://www.fretsonfire.net/forums/viewtopic.php?t=24960 I've also found a bug report for Red Hat (with screenshot): http://bugzilla.redhat.com/show_bug.cgi?id=981758 The workaround is to resize those images to at least 2 pixels. Running this at the ebuild should work: find . -type f -name '*.xpm' -exec identify {} \; | egrep ' 1x' | sed 's/ XPM .*//' | while read f ; do convert "$f" -resize 200%x100%! "$f" ; done find . -type f -name '*.xpm' -exec identify {} \; | egrep 'x1 ' | sed 's/ XPM .*//' | while read f ; do convert "$f" -resize 100%x200%! "$f" ; done Do you want me to submit a patch to icewm-themes, or is this trivial enough to add? (introduces dependency on media-gfx/imagemagick or similar)

Note: the command-lines I posted above are buggy. 'convert' will write the new file before 'find' has finished listing all the files, which means there is a racing condition that can let find re-read and re-list the same file again, which will make 'convert' re-convert it and re-write it to disk, and so on. Adding "| sort" or "| tac" to the pipeline should fix this racing condition. Alternatively, just read from one directory and write the fixed files into another one.
/usr/share/doc/nvidia-drivers-*/html/knownissues.html: Texture seams in Quake 3 engine Many games based on the Quake 3 engine set their textures to use the GL_CLAMP clamping mode when they should be using GL_CLAMP_TO_EDGE. This was an oversight made by the developers because some legacy NVIDIA GPUs treat the two modes as equivalent. The result is seams at the edges of textures in these games. To mitigate this, older versions of the NVIDIA display driver remap GL_CLAMP to GL_CLAMP_TO_EDGE internally to emulate the behavior of the older GPUs, but this workaround has been disabled by default. To re-enable it, uncheck the "Use Conformant Texture Clamping" checkbox in nvidia-settings before starting any affected applications. Are you sure it isn't this bug + workaround?
(In reply to Jeroen Roovers from comment #3) > Are you sure it isn't this bug + workaround? Probably not. Toggling that checkbox before launching icewm had no effect. Maybe because the buggy lies within xorg-server itself, but I really don't know. Also, it is worth noting that IceWM does not use OpenGL, as far as I know. Probably xorg-server-1.13.4 didn't trigger this bug, while 1.14.3 triggers it.
I just backtracked and found this: xorg-server-1.11.4-r3 → Works fine, no bug in IceWM themes. xorg-server-1.12.4-r2 → Invisible titlebar in IceWM (due to 1-pixel image) Debian guys say this bug is caused by the update from 2:1.12.3-1 to 2:1.12.3.902-1. http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=688908 Tested on: * Gentoo Linux amd64 * nvidia-drivers-319.60 * GeForce 9500M GS (unrelated, as this has been reproduced on other hardware as well. Sidenote: I haven't tested later nvidia-drivers because later versions (325.15, 331.29) are unstable to me, they tend hold the kernel too long, breaking the network drivers or just freezing up the system.
Most of the themes seem broken here - the centre of the title bar is (nearly) empty using most of them, preventing both window dragging and viewing the title in most cases.
