From 97722931a976dc3e6603611b8ec48f10920960e4 Mon Sep 17 00:00:00 2001 From: Michael Lutz Date: Wed, 19 May 2021 21:39:58 +0200 Subject: [PATCH] Fix: [OpenGL] Increase timeout when waiting for the GPU to be done with the drawing buffer. The old timeout could be too short if v-sync was on on lower refresh rates. --- src/video/opengl.cpp | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/src/video/opengl.cpp b/src/video/opengl.cpp index ecafeb6138..df0d12d072 100644 --- a/src/video/opengl.cpp +++ b/src/video/opengl.cpp @@ -1150,7 +1150,7 @@ void OpenGLBackend::ClearCursorCache() void *OpenGLBackend::GetVideoBuffer() { #ifndef NO_GL_BUFFER_SYNC - if (this->sync_vid_mapping != nullptr) _glClientWaitSync(this->sync_vid_mapping, GL_SYNC_FLUSH_COMMANDS_BIT, 10000000); + if (this->sync_vid_mapping != nullptr) _glClientWaitSync(this->sync_vid_mapping, GL_SYNC_FLUSH_COMMANDS_BIT, 100000000); // 100ms timeout. #endif if (!this->persistent_mapping_supported) { @@ -1174,7 +1174,7 @@ uint8 *OpenGLBackend::GetAnimBuffer() if (this->anim_pbo == 0) return nullptr; #ifndef NO_GL_BUFFER_SYNC - if (this->sync_anim_mapping != nullptr) _glClientWaitSync(this->sync_anim_mapping, GL_SYNC_FLUSH_COMMANDS_BIT, 10000000); + if (this->sync_anim_mapping != nullptr) _glClientWaitSync(this->sync_anim_mapping, GL_SYNC_FLUSH_COMMANDS_BIT, 100000000); // 100ms timeout. #endif if (!this->persistent_mapping_supported) {
