Suarez <jasuarez@igalia.com>"> Juan A. Suarez</a> <pre>A patch to fix this landed in upstream: commit 47e01e77d8b658606527f048cda786440f7fbe85 Author: Gert Wollny <<a href="mailto:gert.wollny@collabora.com">gert.wollny@collabora.com</a>> Date: Mon Sep 10 12:39:44 2018 +0200 mesa/texture: Also check for LA texture when querying intensity component size Gallium may pick L16A16_FLOAT to represent GL_INTENSITY16F if no intensity format is provided by the driver. However, when calling glGetTexLevelParameteriv(..., GL_TEXTURE_INTENSITY_SIZE, ...) mesa will return a zero size because the actually used format has no intensity channel and as a fallback only the sizes of the red/green channels are checked. Also checking for LA sizes in the allocated texture resolves this problem. v2: Only check alpha channel size and return it (Marek) L and A size are always the same in this case. Fixes (on virgl): ext_framebuffer_multisample-fast-clear GL_ARB_texture_float * Bugzilla: <a class="bz_bug_link bz_status_NEW " title="NEW - Gallium picking A16L16 formats when emulating INTENSITY16 conflicts with mesa" href="show_bug.cgi?id=107832">https://bugs.freedesktop.org/show_bug.cgi?id=107832</a> Signed-off-by: Gert Wollny <<a href="mailto:gert.wollny@collabora.com">gert.wollny@collabora.com</a>> Reviewed-by: Marek Olšák <<a href="mailto:marek.olsak@amd.com">marek.olsak@amd.com</a>> src/mesa/main/texparam.c | 5 +++++ 1 file changed, 5 insertions(+) Can you check if this fixes the problem?</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
