From 84f5dcf4ec7f06a04eb4a4c1c73993e7e21ee27f Mon Sep 17 00:00:00 2001 From: Kristoffer Skau Date: Mon, 27 Feb 2023 13:33:32 +0100 Subject: [PATCH] Increase cache size for QOpenGLTextureCache Currently images that does not fit in the cache will be destroyed, which is unfortunate. 256 MB cache is too small for todays standards, so increasing it to 1 GB. Also adding an environment variable so that it is changeable if required.
