Error displaying fonts (Intel/OpenGL)
Closed, ArchivedPublicKNOWN ISSUE

Description

Dear Blender devs,

I'am amazed of your job that you are doing for free!!
Sadly there is a bug to report:
blender displays the fonts incorrectly.(see screenshots)
I installed the old interface and the fonts worked.
Its probably a driver issue:

Have you tried upgrading your graphics drivers? - We have quite a few reports like this and most are infact issues with buggy drivers.

Moved from Blender 2.6 Bug Tracker to OpenGL errors

This is an OpenGL driver issue. Please make sure you're using latest drivers from Intel's download center (your report says you're using driver 8.14.8.1075 and Intel's site claims that latest driver for this card is 8.14.8.1065, this could happen if i.e. laptop vendor provided his own drivers which could be buggy).

Another option could be to download opengl32.dll from http://download.blender.org/ftp/incoming/softwaregl/ and put it near the blender.exe. It'll make Blender using fully software OpenGL implementation. Unfortunately it'll also make it slower.

Moving to OpenGL tracker.

Yes, the driver is made from the manufacturer Acer. But that is the only bug that has shown so far in the driver. I tested the Opengl plugin and it displays the fonts correctly but it is so slow that I can not use it.
I also tried installing the driver from Intel's website, but it says: Error the driver being installed is not validated for this computer. Please obtain the appropriate driver from the computer manufacturer.


PS: i don't understand why the fonts work on blender 2.49a.

Blender 2.49 is using completely different approach than current;y supported 2.6x series. There was a bug in intel's drivers which made blender unusable after internationalization stuff was commited. I can remember at least one guy fro mthis tracker who just forces to install driver from intel's site ignoring warning and everything worked for him. You can create recovery point and check if it'll work for you.
It's a bug in driver, sometimes it's possible to work around it from blender side when you've got access to buggy setup, but otherwise it's almost impossible.

Couldn't you improve the opengl32.dll and include it in every blender version so that if the native driver fails or is outdated, the internal driver is used?
It's better for the out of the box experience...

@L_S, yes - this would be good, we do on Linux, but making this optional on windows isn't so simple, We could simply include the DLL and have users copy it so its next to blender.exe,

But getting opengl DLL for windows 64bit and 32bit is a bit of work for windows maintainers, +1 for this if they have time :D

but this would solve all the opengl errors on windows!
Or maybe could you write a plugin for directx?
Anyway... so could someone fix this OpenGl error in blender please?

It would solve opengl errors in linux too, but we dont enable because software opengl is incredible slow and unusable in many cases.

using directx isnt really an option and wouldnt help - since there would still be compatibility issues with directx drivers.

since this is a bug in the driver, not blender, we cant fix it.

closing this report, its a known problem but its not in blender.

Do think that blender will work if I would install linux (meego 1.2.0.6) on my computer (dualboot)? Is blender usable on meego?

If you have X11 and opengl libraries it should - though not sure why you would use meego? - fedora/debian/ubuntu/arch/suse.... run blender fine.

Meego is a horrible experience, but it is the only linux version that has drivers for this modell. I already tried ubuntu but it does not have the drivers at all: graphic card doesn't work, ethernet port does not work, sd card port doesn't work, no advanced power management, very short battery life. That why I dislike linux, because the drivers are outdated and are far from working as well as windows drivers. I like android but it doesn't have drivers for my computer either.
