The framebuffer is no longer rotated the wrong way around in Qualcomm's latest development drivers. They did something right, only took them over a year.

// Bug: No Dynamic UBO array object access
|

// Affected Devices: Qualcomm/Adreno
|
|
// Started Version: 14
|
|
// Ended Version: 53
|
|
// Accessing UBO array members dynamically causes the Adreno shader compiler to crash
|
|
// Errors out with "Internal Error"
|
|
// With v53 video drivers, dynamic member access works. But there is a new bug
|
|
// The only time we access UBO array members dynamically is with a conversion
|
|
// int posmtx = int(fposmtx);
|
|
// This line will will posmtx with a seemingly random number and cause issues.
|
|
// Bug still active with v53 until we switch to using integers for the fposmtx attribute

// Bug: Centroid is broken in shaders
|
|
// Affected devices: Qualcomm/Adreno
|
|
// Started Version: 14
|
|
// Ended Version: 53
|
|
// 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: 53
|
|
// 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 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: 13.9 working for me (neobrain).
|
|
// Affected OS: Linux
|
|
// 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
|
|
// This bug only happens when paired with base_vertex.
|
|
// 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: 53
|
|
// 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: 53
|
|
// 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.
|
|
BUG_BROKENSWAP,
|
|
// Bug: glBufferSubData/glMapBufferRange stalls + OOM
|
|
// Affected devices: Adreno a3xx/Mali-t6xx
|
|
// Started Version: -1
|
|
// Ended Version: -1
|
|
// Both Adreno and Mali have issues when you call glBufferSubData or glMapBufferRange
|
|
// The driver stalls in each instance no matter what you do
|
|
// Apparently Mali and Adreno share code in this regard since it was wrote by the same person.

BUG_BROKENBUFFERSTREAM,

// Bug: GLSL ES 3.0 textureSize causes abort
|
|
// Affected devices: Adreno a3xx
|
|
// Started Version: -1 (Noticed in v53)
|
|
// Ended Version: 66
|
|
// If a shader includes a textureSize function call then the shader compiler will call abort()
|
|
BUG_BROKENTEXTURESIZE,
|
|
// Bug: ARB_buffer_storage doesn't work with ARRAY_BUFFER type streams
|
|
// Affected devices: Geforce 4xx+
|
|
// Started Version: -1
|
|
// Ended Version: 332.21
|
|
// The buffer_storage streaming method is required for greater speed gains in our buffer streaming
|
|
// It reduces what is needed for streaming to basically a memcpy call
|
|
// It seems to work for all buffer types except GL_ARRAY_BUFFER
|
|
BUG_BROKENBUFFERSTORAGE,
|
|
// Bug: Intel HD 3000 on OS X has broken primitive restart
|
|
// Affected devices: Intel HD 3000
|
|
// Affected OS: OS X
|
|
// Started Version: -1

|
// Bug: unsync mapping doesn't work fine
|
|
// Affected devices: nvidia driver
|
|
// Started Version: -1
|
|
// Ended Version: -1
|
|
// The nvidia driver (both windows + linux) doesn't like unsync mapping performance wise.
|
|
// Because of their threaded behavoir, they seem not to handle unsync mapping complete unsync,
|
|
// in fact, they serialize the driver which adds a much bigger overhead.
|
|
// Workaround: Use BufferSubData
|
|
// TODO: some windows AMD driver/gpu combination seems also affected
|
|
// but as they all support pinned memory, it doesn't matter
