User interface text becomes invisible (see attached screenshot). This happens quite often for me at seemingly "random" times, however I managed to find a way to reliably reproduce it. Sometimes the text will re-appear after fiddling around, but the text will then look corrupted - leading me to believe this might be related to bug #19997
Steps to reproduce:
* Start blender with defaults
* Select user-preferences from file menu
* Go to file and choose any file browser, text will now dissappear from the blender UI
* Immideately close the file browser with the [X] in the upper corner
* UI text remains invisible
If instead of closing the browser, you select a file/directory the text will sometimes re-appear correctly.
As mentioned this will also happen at other seemingly random times.
System info:
* Windows XP Pro (32 bit)
* Intel Core2 Duo U9400
* GPU: Mobile Intel(R) 4 Series Express Chipset Family
Not sure what exact GPU this is, extract from dxdiag below

Hi,
Seems to be the same bug that #19997, can you test with differents OpenGL options ?
ctrl+alt+u -> system -> windows draw method
Please try with differents options to see what happend.
Thanks,
- Diego
Problem is present with all options: Full, Overlap Flip, Overlap, Triple buffer and Automatic.
Overlap seems to have more problems on my system and doesn't re-draw correctly.
Hi,
I have the same issue with r29532. Each time I open a sub-window, like the user prefs or render in a new window, the main blender window text and/or icons are corrupted or missing.
I however found a way to get the display back to normal: close the sub-window and turn full screen (ALT + F11) a few times.
The issue appears on my 2 computers:
Laptop:
- Processor: Intel Core2 Duo P8400
- Graphic card: Intel Mobile 4 series express chipset
- OS: Windows XP Pro SP3 32 bits
Desktop:
- Processor: Intel Core2 Duo E6300
- Graphic car: ATI Radeon HD 5770
- OS: Windows XP Pro SP3 32 bits
Hi,
Seems to be a problem with the drivers and windows XP 32 bits.
Nathan, can you take a look at this ? there is something we can do ?
Thanks,
- Diego
Duplicate of this bug:

OpenGL texture gets lost on duplicating window, something to do with OpenGL contexts probably.
