glxinfo dump
OpenGL renderer string: Gallium 0.4 on AMD CAPE VERDE (DRM 2.46.0 /
4.8.13-300.fc25.x86_64, LLVM 3.8.0)
01:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc.
[AMD/ATI] Cape Verde XT [Radeon HD 7770/8760 / R7 250X] [1002:683d]
Launching weston from vconsole freezes the display, switching to another
vconsole and killing the process returns to command line.
Launching weston under X opens a window with garbled contents. (attached shot)
Launching glxdemo under X opens a window with yellow square, but background
contains garbled noise. resizing the window causes the yellow square to resize
and render, but with more and more garbage appearing in the background
(attached shots)
Using vlc to play a video after selecting the OpenGL backend produces a fixed
garbled screen while the audio plays fine. (Shot attached)
I've experienced similar issues with other X programs which rely on GL(X?),
where the main screen appears but is completely corrupted.
another issue (related or not) is blurry text rendering in various programs.
I've experienced this with blender (see #38070) and with gnome-shell.
Unlike (as I understand it) in #38070, the text is initially rendered properly
but when focus is lost it is blurred and as the cursor hovers over other
elements in the UI it gets worse and worse. Occasionally the whole UI s redrawn
and all the text snaps back, but it's largely unusable. Using software gl
instead has no such issues. Shot attached, note properly rendered text on left
pane (which has focus) vs. blurred right hand pane (which doesn't have focus).
I've experienced the exact same issues on fc23 which uses mesa 11.x and had
(painfully) switched to catalyst which didn't have these issues. A recent
upgrade to fc25 means I can't use catalyst anymore, and despite several years
passing all these issues have not been resolved in the open source drivers.
Attaching everything I can think of, and glad to provide additional info as
needed.
