To get any behaviour change you've to set QT_XCB_NATIVE_PAINTING.

Package: libqt5gui5 Version: 5.15.1+dfsg-4 Severity: wishlist X-Debbugs-Cc: woebbek...@web.de Dear Maintainer, with X2Go Qt5 apps are much slower than X or GTK apps. But there is a workaround: setting the environment variable QT_XCB_NATIVE_PAINTING. This worked until testing updated to Qt 5.15 because upstream disabled the automatic configuration of this feature in commit 7f948d9effad983477977c3274231401f260c531. So please build Qt5 with -xcb-native-painting to make X2Go users happy again :-) Cheers, André -- System Information: Debian Release: testing APT prefers testing APT policy: (990, 'testing'), (500, 'unstable') Architecture: amd64 (x86_64) Kernel: Linux 5.9.0-2-amd64 (SMP w/8 CPU threads) Kernel taint flags: TAINT_PROPRIETARY_MODULE, TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages libqt5gui5 depends on: ii fontconfig2.13.1-4.2 ii libc6 2.31-4 ii libdrm2 2.4.103-1 ii libegl1 1.3.2-1 ii libfontconfig12.13.1-4.2 ii libfreetype6 2.10.2+dfsg-4 ii libgbm1 20.2.3-1 ii libgcc-s1 10.2.0-19 ii libgl11.3.2-1 ii libglib2.0-0 2.66.3-1 ii libharfbuzz0b 2.6.7-1 ii libice6 2:1.0.10-1 ii libinput101.16.4-1 ii libjpeg62-turbo 1:2.0.5-1.1 ii libmd4c0 0.4.6-1 ii libmtdev1 1.1.6-1 ii libpng16-16 1.6.37-3 ii libqt5core5a [qtbase-abi-5-15-1] 5.15.1+dfsg-4 ii libqt5dbus5 5.15.1+dfsg-4 ii libqt5network55.15.1+dfsg-4 ii libsm62:1.2.3-1 ii libstdc++610.2.0-19 ii libudev1 246.6-4 ii libx11-6 2:1.6.12-1 ii libx11-xcb1 2:1.6.12-1 ii libxcb-glx0 1.14-2 ii libxcb-icccm4 0.4.1-1.1 ii libxcb-image0 0.4.0-1+b2 ii libxcb-keysyms1 0.4.0-1+b2 ii libxcb-randr0 1.14-2 ii libxcb-render-util0 0.3.9-1+b1 ii libxcb-render01.14-2 ii libxcb-shape0 1.14-2 ii libxcb-shm0 1.14-2 ii libxcb-sync1 1.14-2 ii libxcb-xfixes01.14-2 ii libxcb-xinerama0 1.14-2 ii libxcb-xinput01.14-2 ii libxcb-xkb1 1.14-2 ii libxcb1 1.14-2 ii libxkbcommon-x11-01.0.3-2 ii libxkbcommon0 1.0.3-2 ii zlib1g1:1.2.11.dfsg-2 Versions of packages libqt5gui5 recommends: ii libqt5svg5 5.15.1-2 pn qt5-gtk-platformtheme Versions of packages libqt5gui5 suggests: ii qt5-image-formats-plugins 5.15.1-2 pn qtwayland5 -- no debconf information
