enum Bug
{
// Bug: No Dynamic UBO array object access
// Affected Devices: Qualcomm/Adreno
// Started Version: 14
// Ended Version: -1
// Accessing UBO array members dynamically causes the Adreno shader compiler to crash
// Errors out with "Internal Error"
BUG_NODYNUBOACCESS = 0,
// Bug: Centroid is broken in shaders
// Affected devices: Qualcomm/Adreno
// Started Version: 14
// Ended Version: -1
// Centroid in/out, used in the shaders, is used for multisample buffers to get the texel correctly
// When MSAA is disabled, it acts like a regular in/out
// Tends to cause the driver to render full white or black
BUG_BROKENCENTROID,
// Bug: INFO_LOG_LENGTH broken
// Affected devices: Qualcomm/Adreno
// Started Version: ? (Noticed on v14)
// Ended Version: -1
// When compiling a shader, it is important that when it fails,
// you first get the length of the information log prior to grabbing it.
// This allows you to allocate an array to store all of the log
// Adreno devices /always/ return 0 when querying GL_INFO_LOG_LENGTH
// They also max out at 1024 bytes(1023 characters + null terminator) for the log
BUG_BROKENINFOLOG,
// Bug: UBO buffer offset broken
// Affected devices: all mesa drivers
// Started Version: 9.0 (mesa doesn't support ubo before)
// Ended Version: up to 9.2
// The offset of glBindBufferRange was ignored on all Mesa Gallium3D drivers until 9.1.3
// Nouveau stored the offset as u16 which isn't enough for all cases with range until 9.1.6
// I965 has broken data fetches from uniform buffers which results in a dithering until 9.2.0
BUG_BROKENUBO,
// Bug: The hacked buffer upload method isn't working
// This isn't a bug as the hacked buffer itself isn't used to work.
// I'm still surprised that it works on so many drivers.
// Affected devices: - amd close sourced driver
// - nouveau
// - maybe also some others
// This hack is evil. It's like free(pointer); *pointer = data;
BUG_BROKENHACKEDBUFFER,
// Bug: The pinned memory extension isn't working for index buffers
// Affected devices: AMD as they are the only vendor providing this extension
// Started Version: ?
// Ended Version: -1
// Pinned memory is disabled for index buffer as the amd driver (the only one with pinned memory support) seems
// to be broken. We just get flickering/black rendering when using pinned memory here -- degasus - 2013/08/20
// Please see issue #6105 on google code. Let's hope buffer storage solves this issues.
BUG_BROKENPINNEDMEMORY,
// Bug: Entirely broken UBOs
// Affected devices: Qualcomm/Adreno
// Started Version: ? (Noticed on v45)
// Ended Version: -1
// Uniform buffers are entirely broken on Qualcomm drivers with v45
// Trying to use the uniform buffers causes a malloc to fail inside the driver
// To be safe, blanket drivers from v41 - v45
BUG_ANNIHILATEDUBOS,
// Bug : Can't draw on screen text and clear correctly.
// Affected devices: Qualcomm/Adreno
// Started Version: ?
// Ended Version: ?
// Current code for drawing on screen text and clearing the framebuffer doesn't work on Adreno
// Drawing on screen text causes the whole screen to swizzle in a terrible fashion
// Clearing the framebuffer causes one to never see a frame.
