I can confirm that libgtk-3-0 3.24.20-0ubuntu1.1 from focal-proposed fixes the rendering issue.
I have tested with: 1) the attached minimal test case: gcc -o testcase testcase.c `pkg-config --cflags --libs gtk+-3.0` ./testcase 2) a full-blown flutter app: snap install --classic flutter flutter config --enable-linux-desktop flutter create test_app cd test_app flutter run ** Tags removed: verification-needed verification-needed-focal ** Tags added: verification-done-focal -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to gtk+3.0 in Ubuntu. https://bugs.launchpad.net/bugs/1960947 Title: Graphical issues for GtKGL in software rendering Status in gtk+3.0 package in Ubuntu: Fix Released Status in gtk+3.0 source package in Focal: Fix Committed Bug description: * Issue GTK applications using GL graphic show corruption problems under software rendering * Test case 1. install gtk-3-examples 2. $ LIBGL_ALWAYS_SOFTWARE=1 gtk3-demo 3. select the gl example, it should render without issues * Regression potentiel The change is in the GL backend so check for rendering issues in GTK softwares using GL, including flutter applications To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gtk+3.0/+bug/1960947/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
