From 6ff42c2ab2d1edff5bc937eb0f4cea1c9469bcf5 Mon Sep 17 00:00:00 2001 From: Ray Strode Date: Tue, 15 Jan 2019 10:29:55 -0500 Subject: [PATCH] backends/native: update glyph cache on resume As mentioned in a previous commit, the proprietary NVIDIA driver garbles memory on suspend. That behavior, means that clutter's glyph cache (which is stored in GPU memory) gets corrupted on suspend. This commit ensures the glyph cache is blown away when the logind session becomes active (on VT switch and resume). --- src/backends/native/meta-backend-native.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/src/backends/native/meta-backend-native.c b/src/backends/native/meta-backend-native.c index f87c5a066..0730a4acb 100644 --- a/src/backends/native/meta-backend-native.c +++ b/src/backends/native/meta-backend-native.c @@ -653,7 +653,10 @@ void meta_backend_native_resume (MetaBackendNative *native) MetaIdleMonitor *idle_monitor; if (cogl_has_feature (cogl_context, COGL_FEATURE_ID_UNSTABLE_TEXTURES)) - g_signal_emit_by_name (display, "gl-video-memory-purged"); + { + clutter_clear_glyph_cache (); + g_signal_emit_by_name (display, "gl-video-memory-purged"); + } meta_monitor_manager_kms_resume (monitor_manager_kms);
