Priority: medium
Bug ID: 81843
Assignee: idr at freedesktop.org
Summary: ETC2 textures are not returned as compressed images
QA Contact: intel-3d-bugs at lists.freedesktop.org
Severity: normal
Classification: Unclassified
OS: Linux (All)
Reporter: jon at lunarg.com
Hardware: x86-64 (AMD64)
Status: NEW
Version: 10.2
Component: Drivers/DRI/i965
Product: Mesa
i965 driver stores ETC2 textures as uncompressed since Gen 7.5 and earlier
GPUs don't support ETC2 format. glGetCompressedImage() of these ETC2
textures should cause a compression to ETC2 format to occur before returning
data
to the client. This compression on read of ETC2 texture doesn't appear to be
happening.
